The corrugated tube 4 may be turnable together with harness supporting cradles within a cylindrical wall formed in a panel of the car body.

Abstract: A harness slack absorbing apparatus includes a resilient member 6, a harness support member 7 attached to a distal end portion of the resilient member, and a wire harness 4 supported by the harness support member and pushed upward by resilience of the resilient member thereby to absorb a slack of the wire harness. The harness support member 7 includes a recess 8 having a curved shape in cross section, in which the wire harness is held. The harness support member 7 may be provided at its distal end with a curved or inclined face 39 which is continued from the recess in a shape along a bending direction of the wire harness. The recess may have a depth at least larger than a radius of the wire harness. The harness support member may be composed of a support member body and a lid respectively having recesses adapted to be joined together to form a harness insertion bore, so that the wire harness can be held by the member body and the lid along an entire circumference thereof.

Abstract: A wiring harness bending mechanism is provided, which includes: a wiring harness; and first and second link arms each having a tubular portion to put the wiring harness therethrough, wherein a pair of convexities are formed on the first link arm and a pair of concavities to engage the convexities are formed on the second link arm. The first link arm is formed of a pair of first divided link arms connected with a hinge portion and each having a convexity, and the second link arm is formed of a pair of second divided link arms connected with a hinge portion and each having a concavity. A plate portion is provided projectingly from each of the tubular portions, and the pair of convexities are arranged on one end side of one plate portion and the pair of concavities are arranged on one end side of the other plate portion. A fixing portion is provided on each of the other end sides of the respective plate portions for mounting the first and second link arms.

Abstract: A structure of installing a wire harness for a sliding door includes a harness protective tube 2 in which electric wires are contained to compose the wire harness. The harness protective tube 2 is curved at the sliding door side and installed at a vehicle body side. The harness protective tube 2 has an oval shape in cross section, and is curved in a direction of its longer diameter portions 3 at the sliding door side so that the longer diameter portions are positioned in a vertical direction, whereby harness slack absorbing function is imparted to the harness protective tube. The longer diameter portions 3 are supported by a support part 11 at the sliding door side, and the harness protective tube 2 is curved in a direction of the longer diameter portions extending from the support part to the vehicle body side. There is provided a protector 5 in which the support part 11 is positioned, and the harness protective tube 2 is contained in a curved state in a direction of the longer diameter portions 3.

Abstract: The additional segment of a wire harness 3 which is required for opening/closing a slide door 1 and constitutes a curved segment 20 is housed in a protector 9. The protector 9 has curved walls 28, 29, guide rail 30, slider 31 and first and second harness outlets 32, 33. When the slide door 1 is opened/closed, the wire harness 3 shuttles to and fro within the second wire harness outlet 33. The looseness of the wire harness when the slide door is opened/closed may be absorbed in such a manner that it is supported by an elastic member in a state where the wire harness has been curved within the protector without using the guide rail 30 and slider 31. The protecting member may be provided with a bending limiting portion, harness securing portion and flange or slanted sliding-contact portion which serve to slide the wire harness smoothly. In this configuration, it is possible to realize improvement of easiness of assembling, saving of the space and smooth operation of a power supply apparatus.

Abstract: Slidable-contact portions 10, 24 of a fixing tool 1 are engaged with the concave grooves 11 of a corrugated tube 2 which is circular in section so that the corrugated tube is supported rotatably in its circumferential direction by the fixing tool 1. Where the corrugate tube is oval in section, it is fixed inside a rotating member 33 with a circular outer periphery, and the rotating member is held rotatably in its circumferential direction inside a body of the fixing tool 1. The rotating member may be moved along a cam groove, or may hold the corrugated tube in a state decentered in an oblique direction. The fixing tool 1 is composed of a receiving part 3 and covering part 2 which have slidable-contact supporting portions 10, 24 to be engaged with the concave grooves 11 of the corrugated tube 2.

Abstract: In a power supply structure in a sliding structure, the one end of a wire harness 3 is secured to either one of a sliding structure 1 and a body 5. The other end of the wire harness 3 is hung over the other of them. An elastic member 4 is arranged along the wire harness in the longitudinal direction from the one end of the wire harness so that the wire harness is supported by the elastic member. The elastic member 4 may be a lengthy flat spring. The elastic member may be composed of a first spring segment along the outer face of the wire harness and a second spring segment having a small spring constant which protrudes toward a free end of the elastic member. The elastic member may be bent at an intermediate position in the longitudinal direction and arranged on the curved portion of the wire harness. The elastic member may be composed of a flat spring segment along the inner face of the curved portion and a spiral segment. The elastic member may be provided with a harness supporting member.

Abstract: The connector coupling structure includes a connector frame 7 which has a connector 11 and a pillar-shaped projection 9 with a height higher than the connector 11 both being formed on the same face and a connector frame 3 which has a groove portion 16 in which the entirety of the connector frame 7, the connector 11 and the pillar-shaped projection 9 can be inserted. The bottom wall 19 of the groove portion 16 is configured so as to be slanted in a manner that the depth thereof becomes shallower toward the inner portion thereof from the opening position thereof. A connector 21 is provided at the inner side of the bottom wall 19 in opposite to the connector 11. The bottom wall 19 is provided at the opening side thereof in opposite to the pillar-shaped projection 9 with a hole 25 with a bottom wall in which the pillar-shaped projection 9 is inserted.

Abstract: A connector fitting structure comprises a first connector in which an opening is defined by notching a front end portion of one side wall thereof, a second connector fitted with the first connector, an initial fitting member capable of retaining provisionally the second connector inside the first connector, and final fitting means for urging the second connector in a first direction to fit with the first connector, wherein a front end portion of the second connector is inserted from the opening into inside of the first connector along a second direction perpendicular to the first direction and provisionally retained by the initial fitting member, thereafter the second connector is fitted with the first connector by the final fitting means.
