BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a rear part structure for a vehicle, for installing a tailgate in a so-called mohican roof having a groove (mohican groove) extending in the forward and rearward direction of a vehicle at a connection portion between a roof panel of the vehicle body and a side frame thereof.

2. Discussion of Background Art

Conventionally, a hatchback tailgate composed of a hinge structure is provided in a recreation vehicle (RV) such as a minivan or a station wagon in order to easily place loads in the rear part of the vehicle. For example, refer to Japanese Unexamined Patent Publication No. 2001-105867 (paragraphs 0021 through 0022, and FIG. 12 and FIG. 13).

FIG. 1 is a view showing a prior art rear part structure of a vehicle, which is a sectional view showing the major parts in a state where the tailgate is closed.

As shown in FIG. 1, a tailgate 330 is installed so as to be vertically pivotable via a hinge 310 at the rear part 302 of a roof portion 301 of a vehicle body 300. A hinge pin 325 which becomes a rotating center of the hinge 310 axially supporting the tailgate 330 is disposed between the roof portion 301 and the tailgate 330. The hinge 310 is composed of a hinge base member 315 fixed on the roof portion 301 and a gate hinge member 320 fixed on the tailgate 330. The hinge 310 is installed at both left and right sides of the upper part of the gate opening portion 303 formed in the rear section 302 of the vehicle body 300, and pivotally supports the tailgate 330 so as to open it in the form of a pop-up system.

The hinge base member 315 is a metal plate member which is roughly L-shaped in its side view. A fixing portion 316 at the base end side is firmly attached to an upper part 304 of the gate opening portion 303 of the vehicle body 300 by means of a welding bolt attachment member 335, and a connection portion 317 at the tip end side is rotatably connected to the gate hinge member 320 by the hinge pin 325. The fixing portion 316 is fixed on a flat upper part 304 lower by a height L2 from the ceiling surface 305 of the roof portion 301.

The gate hinge member 320 is fixed, by a gate attaching bolt 340, on a roughly vertical attaching surface 332 where the fixing portion 321 at the base end side is formed on an upper part 331 of the tailgate 330, and a connection 322 at the tip end side is rotatably connected to the hinge base member 315 by the hinge pin 325.

When the tailgate 330 is opened, the tailgate 330 is turned in the direction of the arrow A centering around the hinge pin 325. At this time, parting edge 333 on the upper part of the tailgate 330 and the gate hinge member 320 are caused to turn integral with the tailgate 330, and the parting edge 333 turns in the direction of the arrow A and is caused to approach the fixing portion 316 of the hinge base member 315.

At this time, in order to prevent the parting edge 333 from being brought into contact with the roof portion 301, it is necessary for the hinge pin 325 to be disposed at a higher position by lengthening the arm length L1 at the hinge base member 315 which supports the gate hinge portion 320. By lengthening the arm length L1 of the hinge base member 315, it is necessary that, in the vehicle body 300, the length L2 from the installation plane of the upper part 304 on which the fixing portion 316 is provided to the ceiling surface 305 is lengthened, and the profile of the roof portion 301 is set in order to avoid the rotating locus of the parting edge 333 of the tailgate 330.

In line therewith, in the vehicle body 300, the thickness T1 from the upper end of the gate opening portion 303 in its upper direction to the ceiling surface 305 is increased, wherein the height H1 of the gate opening portion 303 in its upper direction is regulated, and the entire area of the gate opening portion 303 is narrowed. Therefore, in the gate opening portion 303, it becomes difficult to carry out loading a large load in or unloading the same from the luggage compartment because the height H1 is low.

Also, for a person in charge of loading or unloading, there is a fear that his or her head is brought into contact with the edge of the gate opening portion 303 during the loading or unloading since the inside upper end of the gate opening portion 303 is low.

In addition, where the tailgate 330 is attached to the vehicle body 300, it is possible to adjust the attaching position thereof in the top and bottom directions of the arrow B by making a through-hole 323, into which a gate attaching bolt 340 is inserted, into a slot longer in the top and bottom directions.

However, where the attaching position of the tailgate 330 is adjusted in the longitudinal (forward/backward) direction of the arrow C, since the fixing portion 316 of the hinge 310 is firmly fixed with rivets or welding bolts attachment members 335 so that the tailgate 330 does not raffle, it is necessary to modify the roof portion 301 of the vehicle body 300 or change the shape of the hinge 310. Therefore, with respect to the tailgate 330, it has been difficult to adjust the attaching position thereof in the longitudinal direction of the arrow C.

Further, an open stay stays (not illustrated) is which hold the tailgate in an open position, or open stays, are provided between the tailgate 330 and the vehicle body 300. The one end First ends of the open stay is stays are respectively supported at both opposite sides of the tailgate 330 and the other end ends thereof is are respectively supported at both opposite sides of the gate opening portion 303 in the vehicle width direction, respectively. And, the attaching position positions of the open stay stays (not illustrated) intervening provided between the tailgate 330 secured at the end portion in the vehicle width direction of and the gate opening portion 303 and the vehicle body 300 is are offset from the hinge hinges 310 in the vehicle width direction of the tailgate 330.

Therefore, there is a possibility for the tailgate 330 to be deformed so as to be distorted due to a reaction force of the open stay (not illustrated). Deformation of the tailgate 330 adversely influences the assembling dimensions, wherein there is a problem in that it takes many working hours for adjustment of the dimensions and composition.

It is a first object of the invention to provide a rear part structure of a vehicle by which larger dimensions can be secured with respect to the top and bottom directions of the gate opening portion of the tailgate, with respect to hinge means for a tailgate.

On the other hand, since the open stay (not illustrated) maintains an opened state of a tailgate when the tailgate being a heavy load is opened upwards, there are many cases where the open stay intervenes between the vehicle body and the tailgate for supporting the tailgate. As has been described in Japanese Unexamined Patent Publication No.2000-158942 (Paragraph 0009 and FIG. 7), a damper stay may be listed as a detailed example of the open stay, which carries a function for relieving a force when manually opening the tailgate upwards. Open stays such as a damper stay may be provided at both side ends of the tailgate as a pair. However, in recent years, taking economical efficiency of a vehicle into consideration or taking convenience into consideration with respect to the open stay be coming an obstacle in loading or unloading, there are many cases where the open stay is provided only at one side end of the tailgate.

In the case where open stays are provided at both side ends, reaction forces received from the respective open stays are added to the tailgate uniformly at both the left and right sides when an opening or closing operation is carried out or the tailgate is fully opened. However, in the case of a tailgate for which an open stay is provided only at one side end portion, the reaction force is centralized only at the side where the open stay is provided. Resultantly, where the attaching positions of the above-described pair of hinge members are made completely symmetrical with respect to the left and right sides, there is a problem in that, when the tailgate is assembled in a vehicle body, the side where no open stay is attached falls due to its own weight and is deflected, and a difference in level gap or deviation is apt to occur between the left and right sides of the tailgate.

In such cases, in the prior arts, adjustment work is required so as to absorb the above-described difference in level gap or deviation when assembling the tailgate and open stays in the vehicle body. A method for employing a so-called expectancy allowance, for example, adding an adjustment shim to one hinge member, was adopted as a detailed example. However, the adjustment work using such a shim results in a lowering in work efficiency, in particular, assembling work under a premise of such an expectancy allowance accompanies a difficulty in view of quantitativity and stability, and requires skill to some extent. In addition, in a case of complex component composition such as a tailgate and open stays, etc., it becomes difficult to accurately analyze the expectancy allowance.

Therefore, it is a second object of the invention to provide a rear part structure of a vehicle which does not require any adjustment work of shims, etc., and can easily early out assembling work of the tailgate.

Further, the tailgate is supported so as to be opened and closed by a tailgate hinge axially supported at the upper part of the opening portion. In Japanese Unexamined Patent Publication No. 2001-105867 described above, as shown in FIG. 2, a rear part structure that can vertically open and close a tailgate T by a tailgate hinge H axially supported at the rear end of a roof panel R so as to be rotatable is illustrated.

Conventionally, where a tailgate hinge is disposed outside a vehicle compartment, the tailgate hinge H is covered up by a spoiler SP or a resin-made garnish, as shown in FIG. 3, in view of the appearance of the vehicle or in order to avoid the exposure of the hinge to the outside of the vehicle. However, where the tailgate hinge H is covered up by the spoiler SP, etc., it is necessary to cover up the entirety of a tailgate hinge even for a tailgate hinge that seems to be sufficient to be partially outfitted in an attempt to secure harmony with respect to the entire appearance. For this reason, there is no way other than to employ a large-type resin component, wherein appearance matching with the surrounding components thereof becomes difficult, and there are some problems in that production costs are increased, and the number of steps is increased in the production process due to an increase in the number of components.

In addition, a tailgate hinge may be provided at the rear part of a vehicle or at the tailgate without using any outfitting components such as a spoiler, garnish, etc. For example, as shown in FIG. 4, the upper part of the roof panel R is formed to be bulge-shaped, and a tailgate hinge is accommodated in the bulge-shaped projection BG so that the tailgate is not exposed to the outside of a vehicle. However, in the case where the tailgate hinge is covered up at the rear part of a vehicle or at the tailgate side without using any outfitting components, the press-forming performance in production of roof panels may be worsened due to addition of some shapes onto the roof side, depending on the design shape. Therefore, it cannot be said to be convenient in view of design and production efficiency.

Further, a tailgate hinge may be disposed in a vehicle compartment. However, the appearance inside the vehicle compartment may be spoiled, although this depends on the positions of where it is disposed. Therefore, it is necessary to attach a hinge cover to cover up the tailgate hinge. For example, where a tailgate hinge is provided in the rear part of a vehicle compartment, it is necessary to attach a hinge cover in order to keep the appearance satisfactory inside the vehicle compartment. For this reason, the design inside the vehicle compartment is subjected to some limitations, resulting in inconvenience in production.

Therefore, it is a third object of the invention to provide a rear part structure of a vehicle, which attaches a tailgate hinge for axially supporting a tailgate to a roof panel without spoiling the vehicle appearance.

SUMMARY OF THE INVENTION

In order to achieve the first object, there is provided a rear part structure of a vehicle according to a first aspect of the present invention, which includes a groove formed in a longitudinal direction of the vehicle at a junction portion of a roof panel and a side frame of the vehicle and in which a tailgate to be installed at a rear part of the vehicle is attached by hinge; wherein the hinge comprises: a hinge base member attached into the groove; and a gate hinge member attached to the tailgate which is pivotally attached to the hinge base member.

According to such a rear part structure of a vehicle, by providing a hinge base member in the groove, the hinge means can be formed such that the rotating locus of the parting of the tailgate does not interfere with the roof panel of a vehicle. Therefore, it is possible to increase the dimension in the top and bottom directions of the gate opening portion that is opened and closed by the tailgate.

In addition, since the hinge is provided in a groove disposed in the left and right end portions of the roof portion of a vehicle, it is possible to increase the supporting interval of the tailgate. Therefore, the attaching strength of the tailgate can be increased.

In the aforementioned rear part structure of a vehicle, the gate hinge member may extend along a direction where the tailgate is opened and closed.

With such a construction, since the gate hinge member extends along the direction where the tailgate is opened and closed, a shearing force acts on the longitudinal plane direction of the gate hinge member at the time of opening and closing the tailgate. Therefore, the gate hinge member can be decreased in its outer shape and plate thickness. With this thin and small-sized gate hinge member, it is possible to reduce the weight and cost of the rear part structure. Further, since the gate hinge member attached to the tailgate is thin and compact, the hinge member does not protrude from the tailgate toward the interior of the vehicle. This leads to a good appearance as well as a sufficiently large space of the gate opening in the vehicle width direction. Therefore, loading and unloading of baggage can be facilitated.

In the aforementioned rear part structure, the gate hinge member may be attached to a side plane portion of the tailgate.

With such a construction, since the gate hinge member is attached to a side plane portion of the tailgate, the attaching work of the gate hinge member can be carried out on the side of the tailgate. Therefore, the worker can easily recognize and check the attaching position of the gate hinge member. Since the attaching work of the gate hinge member can be easily carried out while adjusting positions of the tightening bolts, efficiency of the attaching work can be improved.

Force acts on the fixing position of the gate hinge member and the tailgate not in a direction where the gate hinge member is removed from the tailgate at the time of opening and closing the tailgate but in the shearing direction. Therefore, bolts can provide a sufficiently great fixing strength. Since the hinge is required to withstand a large number repeated uses, the gate hinge member provides sufficient strength and durability for such repeated use.

In the aforementioned rear part structure, the gate hinge member may be adjustable in the longitudinal direction or the vertical direction of the vehicle with respect to the tailgate.

With such a construction, since the gate hinge member is adjustable in the longitudinal direction or the vertical direction of the vehicle with respect to the tailgate, it is possible to adjust an attachment position of the tailgate to eliminate unevenness of attachment errors. Therefore, the tailgate can be accurately attached at a predetermined position.

In the aforementioned rear part structure, one end of an open stay for fixing the tailgate may be provided in the vicinity of attached to the side plane portion of the tailgate, and an attaching portion of the gate hinge member is also attached to the side plane portion of the tailgate.

With such a construction, since the open stay is installed in the vicinity of the attaching portion of the gate hinge member, it is possible to reduce the offset amount between the attaching position of the open stay and hinge. Therefore, a moment applied by the open stay and the gate hinge member at the time of opening and closing the tailgate can be decreased, it is possible to prevent deformation of the tailgate as much as possible.

In the aforementioned rear part structure, the hinge base member may be covered by a hinge cover continuously extending from a roof moulding secured in the groove.

With such a construction, since the hinge base member may be covered by a hinge cover continuously extending from a roof moulding secured in the groove, the hinge cover can be positioned in conformity with the shape of the roof moulding with the gate hinge base unseen, thereby improving the appearance.

By the aforementioned rear part structure of a vehicle according to the first aspect of the invention, since a hinge base member is provided in the groove, the hinge base member can be formed such that the rotating locus of the tailgate does hot interfere with the roof panel of the vehicle body. Therefore, it is possible to increase the size of the gate opening in the vertical direction.

The hinge is provided with a gate hinge member extending along the direction where the tail gate is opened and closed, and the gate hinge member is attached to a side plane portion of the tailgate. It is therefore possible to reduce the thickness of the gate hinge member to increase the size of the gate opening in the vehicle width direction. Therefore, loading and unloading of baggage can be facilitated. Further, the gate hinge member is attached to a side plane portion of the tailgate. This can improve visibility of the worker at the attaching position of the gate hinge member, thereby improving workability for attaching the gate hinge member.

Further, since the hinge is secured in the groove positioned at the left and right end portions of the roof of the vehicle body, it becomes possible to increase the left and right supporting interval of the tailgate, increasing the attaching strength of the tailgate.

Since a shearing force acts on the longitudinal plane direction of the gate hinge member at the time of opening and closing the tailgate, the gate hinge member can be decreased in its outer shape and plate thickness. With this thin and small-sized gate hinge member, it is possible to reduce the weight and cost of the rear part structure.

Furthermore, since the hinge base member is covered by a hinge cover continuously extending from a roof moulding secured in the groove, the hinge cover can be positioned in conformity with the shape of the roof moulding with the gate hinge base unseen, thereby improving the appearance as well as decreasing wind noise upon driving the vehicle.

In order to achieve the second object, there is provided a rear part structure of a vehicle according to a second aspect of the present invention, comprising: a tailgate pivotally supported by a pair of hinge members with an upper edge of the tailgate positioned near a rotating axis of the hinged members such that the tailgate pivots in a vertical direction for opening and closing a rear part of the vehicle; and only one open stay provided at one side part of the tailgate and supporting the tailgate when the tailgate is opened upwards; wherein the respective hinge members have one end thereof connected to provided at the rotating axis at a vehicle body side and the other end thereof connected to a tailgate side via a gate attaching portion, and when the tailgate is closed, the gate attaching portion positions below the rotating axis; and when the tailgate is closed, the gate attaching portion of the hinge member at a side where the pen open stay is mounted is set to position below the gate attaching portion of the other hinge member.

According to such a rear part structure of a vehicle, a deviation between the right and left sides of the tailgate resulting from a reaction force from the open stay can be absorbed in advance by the hinge member per se. To be more specific, adjustment work by means of shims, etc. is not required for the correction of a deflection at the side where the open stay is not provided, because the amount of the deviation can be absorbed by the hinge member per se. Therefore, when assembling the tailgate in a vehicle body or when attaching the open stay, adjustment work is not required, leading to improved working efficiency.

In the aforementioned rear part structure, each of the hinge members may extend along a respective plane including a direction parallel to directions in which where the tailgate is opened and closed, and the gate attaching portion may be formed as a gate attaching hole passing through in a width direction of the vehicle.

With such a construction, when the tailgate is opened and closed, a load acts on the plane direction where the each hinge member extends. Therefore, it is possible to provide a sufficient strength against this opening/closing load. As the result, the hinge member can be decreased in its outer shape and plate thickness, leading to reduced weight and cost reduction.

In the aforementioned rear part structure, the hinge member members may be fixed at each side plane portion of the tailgate via the gate attaching portion portions thereof.

With such a construction, since assembling work of the hinge member can be carried out at a lateral position of the tailgate, which becomes an open space, the assembling work can be easily carried out. It is also possible to improve visibility of the attaching position of the hinge member with respect to the tailgate. Further, force acts on the fixing position of hinge member and the side plane portion not in a direction where the gate hinge member is removed from the tailgate at the time of opening and closing the tailgate but in the shearing direction. Therefore, a bolt or the like can provide a sufficiently great fixing strength.

In the aforementioned rear part structure, the hinge member may be adjustable in longitudinal and vertical directions of the vehicle with respect to the tailgate.

With such a constructions, since when attaching the tailgate to the hinge members, it is possible to readily adjust the attachment position of the tailgate to eliminate unevenness of attachment errors. Therefore, the accuracy for assembling the hinge member and the tailgate can readily be improved.

In the aforementioned rear part structure, the hinge member members may be secured in a groove respective grooves formed as a pair at right and left sides of a roof panel of the vehicle.

With such a construction, it is possible to prevent the attaching portion of the hinge member from protruding from the roof panel. In this instance, for example, as in one preferred embodiment of the present invention, the attachment position of the hinge member can be covered by the hinge cover, which also improves the appearance design.

By the rear part structure of a vehicle according to the second aspect of the present invention, a deviation between the right and left sides of the tailgate resulting from a reaction force from the open stay can be absorbed in advance by the hinge member per se. To be more specific, adjustment work by means of shims, etc. is not required for the correction of a deflection at the side where the open stay is not provided, because the amount of the deviation can be absorbed by the hinge member per se. Therefore, when assembling the tailgate in a vehicle body or when attaching the open stay, such adjustment work is not required, leading to improved working efficiency.

In order to achieve the third object, there is provided a rear part structure of a vehicle according to a third aspect of the present invention, comprising a tailgate; hinge members arranged at both upper right and upper left ends of a rear opening portion of the vehicle to pivotally open and close the tailgate; wherein each tailgate hinge member includes: a hinge base member fixed on a rear end bottom portion of a groove, which extends longitudinally of the vehicle at a junction portion between a side edge of a roof panel and an upper edge of a side frame, and which opens upwards to have a channel-shaped section; and a gate hinge portion mounted on the tailgate and pivotally supported by the hinge base member; and wherein a hinge cover for covering an upper part of the hinge base member is fitted into the groove.

According to such a rear part structure of a vehicle, in a vehicle including a so-called mohican roof, at which a groove extends in the longitudinal direction of the vehicle at a junction portion between a side edge of a roof panel and an upper edge of a side frame and opens upwards to have a channel-shaped section, the tailgated tailgate, to which is attached the gate hinge portion pivotally supported by the hinge base member, can be supported to open and close the rear opening portion of the vehicle. Also, the upper part of the hinge base member is covered by the hinge cover fitted in the groove. Therefore, it is possible to prevent the tailgate hinge member from being exposed to view without spoiling the appearance of the vehicle.

In the aforementioned rear part structure, the hinge cover may include an outer surface, which is connected to a rear end of a roof moulding fitted in the groove, and which is substantially flush with an outer surface of a rear part of the vehicle.

With such a construction, the outer surface of the hinge cover is connected to the rear end of the roof moulding fitted in the groove and is substantially flush with the outer surface of the rear part of the vehicle. Therefore, the outer surface of the hinge cover and the outer surface of the rear part of the vehicle form a unitary design appearance, improving the external appearance of the vehicle.

In the aforementioned rear part structure, the outer surface of the hinge cover may have a design appearance which is substantially continuous from with an outer appearance of an outer surface of a roof moulding fitted in the groove.

With such a construction, since the outer surface of the hinge cover has a design appearance which is substantially continuous with that of an outer surface of the roof moulding, the roof moulding fitted in the groove and the hinge cover form a unitary design appearance, improving the external appearance of the vehicle.

In the aforementioned rear part structure, the hinge cover may be connected to a rear end of the roof moulding so as to allow a relative displacement of the hinge cover with respect to a longitudinal direction of the roof molding.

With such a construction, since the hinge cover is connected to a rear end of the roof moulding so as to allow a relative displacement of the hinge cover with respect to the longitudinal direction of the roof molding, assembly of the hinge cover and other members, such as the roof moulding, and the hinge base member of the tailgate hinge member, can be improved.

In the aforementioned rear part structure, the hinge cover may have positioning ribs along a longitudinal direction thereof and at both ends in a width direction of an underside thereof extending along side portions of the cover. The positioning ribs are brought into contact with the side edge of the roof panel and the upper edge of the side frame, and allow an adjustment of a position of the hinge cover.

With such a construction, the positioning ribs provided along the longitudinal direction and at both ends in the width direction of the underside of the hinge cover abut on the side edge of the roof panel and the upper edge of the side frame, thereby reliably supporting the both ends of the hinge cover in its width direction to prevent swing of the hinge cover in its width direction.

In the aforementioned rear part structure, the hinge cover may include an engagement portion engaged with and secured at a single cover attaching portion of the hinge base member.

With such a construction, by the engagement between the cover attaching portion of the hinge base member and the engagement portion of the hinge cover, the hinge cover can be readily assembled to the hinge base member. Further, with the minimum number of fixing parts, it is possible to restrict cost and complexity of the structure.

Furthermore, there is provided a method for attaching a tailgate hinge member according to a third aspect of the present invention, which comprises the steps of: fixing a hinge base member of a tailgate hinge member on a rear end bottom portion of a groove, which extends longitudinally of a vehicle at a junction portion between a side edge of a roof panel and an upper edge of a side frame, and which opens upwards to have a channel-shaped section; thereafter connecting one end of a hinge cover for covering the corresponding hinge base member to a rear end of a roof moulding fitted in the groove; and engaging the other end of the hinge cover with a cover attaching portion of the hinge base member.

According to such a method, since one end of the hinge cover is connected to the rear end of the roof moulding, and the other end of the hinge cover is engaged with the cover attaching portion of the hinge base member, the assembly of the hinge cover can readily be made.

By the rear part structure of a vehicle according to the third aspect of the present invention, the upper part of the hinge base member is covered by the hinge cover fitted in the groove of the mohican roof. This can improve the external appearance of the vehicle while preventing the tailgate hinge member from being exposed to view. Further, the hinge cover for covering the hinge base member may be small-sized to be sufficient for being fitted into the groove. Therefore, large-sized plastic components or the roof panel with a special structure are not required, which leads to improved formability and reduced cost. Further, since there is no need to provide a large plastic part or a roof panel with a special structure, the design freedom of the vehicle can be improved.

The Each hinge member 102 is formed of, for example, a steel plate pressed article, and in the present embodiment, it is formed to be a roughly flat plate-shaped member. The plate surface thereof extends almost on the along a respective plane including parallel to the opening and closing directions of the tailgate 101, that is, a perpendicular plane along parallel to the longitudinal direction of the vehicle.

In the tailgate 101, as shown in FIG. 13, the side plane portion portions 101a, 101a is are formed in the vicinity of the left and right edge portions at the plane side facing the inside of the vehicle compartment so that it is erected they extend toward the inside of the compartment and along the vertical direction of the tailgate 101. (In FIG. 13, only the right side plane portion 101a is shown). The tailgate 101 is attached in the form that the each side plane portion 101a is brought into facial contact with the gate supporting portion 102b of the corresponding hinge member 102. Concretely speaking, as shown in FIG. 15, the each hinge member 102 is slightly bent and formed so that it becomes roughly elbow-shaped in its side view, and the recess portion side thereof is disposed so as to face the inside of the compartment, wherein the each gate supporting portion 102b is connected to the upper part of the corresponding side plane portion 101a of the tailgate 101.

As shown in FIG. 15A, the gate supporting portion 102b of each hinge member 102 includes a gate attaching portion 121 which is positioned at the upper edge side of the tailgate 101 and a gate attaching portion 122 which is positioned downward of the gate attaching portion 121 are provided in the gate supporting portion 102b with the tailgate 101 fully closed. With the tailgate 101 fully closed, the gate attaching portions 121 and 122 are positioned downward of the rotating axis 111, and in the present embodiment, these components are located at the rearward side of the vehicle more than the rotating axis 111 of the corresponding hinge member 102. Further, in the embodiment, the gate attaching portions 121 and 122 are formed as gate attaching holes that pass through in the width direction of the vehicle, whereby the tailgate 101 is connected to and fixed at the hinge member members 102, 102 by fixing bolts (not illustrated) in the portion portions of the side plane portion portions 101a, 101a thereof via the respective gate attaching portions 121 and 122 formed as holes. Further, insertion holes 123 and 124 of bolts for provisionally fixing a fixture (not illustrated) used to attach the tailgate 101 are drilled between both the gate attaching portions 121 and 122.

The present invention is mainly featured in that, in a state where the tailgate 101 shown in FIG. 15A is closed, the positions of the gate attaching portions 121 and 122 of the hinge member 102 at the side where the open stay 103 (FIG. 13) is provided are set downward of the positions of the gate attaching portions 121 and 122 of the other hinge member 102. FIGS. 15(a), and 15(b) are views, partly in cross section, showing a side section of the vehicle as described above. Therefore, in the these side views, it seems that the pair of hinge members 102 appear to overlap each other. Therefore, in the following description, a description is based on the hinge member 102 shown in FIG. 15(a) (that is, this is a hinge member positioned at the left side of a vehicle, which is the hinge member at the side where the open stay 103 (FIG. 13) is not provided) being given a reference number 102A, the distance dimensions thereof are given reference numbers L7 and L9 while the hinge member 102 positioned at the deep side of the paper (that is, this is a hinge member positioned at the right side of the vehicle, which is the hinge member at the side where the open stay 103 is provided) is given a reference number 102B and the distance dimensions thereof are given reference numbers L8 and L10.

The distance dimensions L8 and L10 with respect to the perpendicular direction between the center of the rotating axis in the hinge member 102B and the respective gate attaching portions 121 and 122 (respectively indicating the center of the hole) are set to greater values than the same distance dimensions L7 and L9 in the hinge member 102A. That is, since the positions of the rotating axes 111 in both the hinge members 102A and 102B are set to the same height, the positions of the gate attaching portions 121 and 122 of the hinge member 102B are located downward of the positions of the gate attaching portions 121 and 122 of the hinge member 102A. In the present embodiment, for example, the distance dimensions L8 and L10 at the hinge member 102B side are, respectively, set to 23.1 mm and 79.4 mm while those L7 and L9 at the hinge member 102A side are, respectively, set to 22.5 min and 78.7 mm. That is, the respective hinge members 102A and 102B are formed so that dimensional differences are produced by 0.6 mm at the gate attaching portion 121 and by 0.7 mm at the gate attaching portion 122.

Thus, if, with the tailgate 101 closed, the hole positions of the gate attaching portions 121 and 122 at the hinge member 102B side are set to be lower than the hole positions of the other side, and are set to so-called left-right asymmetrical hole positions, it is possible, in an assembling process of the open stay 103, to absorb a deviation error without requiring any adjustment work, for example, by using a shim, etc., with respect to correction of the deviation between the left and right sides of the tailgate 101, which results from a reaction from the open stay 103, in detail, a deflection at the side where the open stay 103 is not provided. Therefore, when assembling the tailgate 101 in the vehicle body 104 or attaching the open stay 103, no adjustment work is required, wherein working efficiency can be improved.

Therefore, it is possible to secure strength against the opening and closing load. Accordingly, the outer shape and plate thickness of the hinge member members 102, 102 can be reduced, wherein weight and production costs can be reduced.

Further, by attaching the hinge member members 102, 102 to the side plane portion portions 101a, 101a of the tailgate 101, assembling work of the hinge member members 102, 102 can be carried out at a lateral position of the tailgate 101, which becomes an open space, wherein the assembling work can be easily carried out, and the detailed attaching point of the each hinge member 102 with respect to the tailgate 101 can be visually confirmed. In addition, such a structure can be obtained, in which, when the tailgate 101 is opened and closed, a force is added applied to the fixing portion portions of the hinge member members 102, 102 and the side plane portion portions 101a, 101a not in the direction along which the hinge member members 102, 102 is are peeled off from the tailgate 101 but in the shearing direction thereof. Therefore, it is possible to obtain large fixing strength by tightening means such as bolts.

Also, if such a structure is employed, in which the hinge member members 102, 102 is are provided in the groove grooves 108, 108 which is are recessed with respect to the roof panel R, it is possible to prevent the attaching portion portions of the hinge member members 102, 102 from protruding from the roof panel R. In this case, for example, as in the present embodiment, by attaching the hinge cover covers 110, 110 to the groove grooves 108, 108, it is possible to cover up the attaching portion of the each hinge member 102, wherein appearance design thereof can be improved.
