Abstract: A support mount bracket (57) provided on a vehicle frame (9) and configured to support a mount part (53) of a front differential gear unit (36) is arranged on part of a cross-member (12) connecting a pair of right and left main frames (10) so as to be, in a vehicle width direction, displaced from the center of a vehicle (1) in a width direction thereof. The support mount bracket (57) includes a base part (57d, 57e) to be connected to the cross-member (12), and a pair of fixing parts (57b, 57c) protruding from the base part (57d, 57c) and sandwiching the mount part (53) from sides thereof in the vehicle width direction. One (57b) of the fixing parts (57b, 57c) on a side closer to the center of the vehicle (1) in the width direction thereof is detachably attached to the base part (57d).

Abstract: An exhaust-gas purification device disposition structure of a vehicle, comprises a fuel tank with a fuel supply port which is disposed so as to be open to an outside of a vehicle compartment, and a urea tank to accommodate urea water solution as deoxidizer to purify exhaust gas. The urea tank is disposed outside the vehicle compartment, and a pouring port of the urea tank is provided inside the vehicle compartment. Accordingly, the urea water solution can be surely prevented from entering into the vehicle compartment even in case of the breakage of the urea tank, and the mistake of supplying the wrong liquid into the wrong supply (pouring) port tank which may be made by confusing the ports can be avoided.

Abstract: An underbody structure of a vehicle includes a floor panel of which rear portion is raised to form a rear floor, a pair of left and right rear side frames extending generally along a longitudinal axis of the vehicle at the rear of the floor panel with a specific distance held between the left and right rear side frames across the vehicle, and a rear cross member extending widthwise across the vehicle and interconnecting forward end portions of the left and right rear side frames. A fuel tank is mounted between the left and right rear side frames, and the rear cross member is located under the floor panel at the front of the fuel tank.

Abstract: Disclosed is an automobile underbody structure, wherein a pair of laterally-spaced floor frames 10 are disposed to extend longitudinally in such a manner as to interpose a tunnel region 6 of a front floor portion 2 therebetween and joined to a bottom surface of the front floor portion 2, and a cross member 15, 16 is disposed to extend laterally so as to connect each side-sill 7 and the tunnel region 6 and joined to a top surface of the front floor portion 2. Each of the floor frames 10 is gradually inclined laterally inward toward the rear end thereof so as to be obliquely disposed relative to the cross member 15, 16 in top plan view. A rearward displacement of the floor frames 10 during a head-on collision exerts a compressive force on a region of the cross member 15, 16 located on the laterally outward side relative to each of the floor frames 10, and a tensile force on a region of the cross member 15, 16 located on the laterally inward side relative to each of the floor frames 10.

Abstract: Disclosed is an underbody structure for an automobile, which comprises a pair of laterally-spaced floor frames 10 disposed to extend longitudinally in such a manner as to interpose a tunnel region 6 therebetween and joined to a bottom surface of a front floor portion 2. Each of the floor frames 10 has a rear end located in the vicinity of a rear kick-up portion 3 extending upward from a rear end of the front floor portion 2. The rear kick-up portion 3 and each rear end region of the floor frames 10 are connected to one another from the exterior side of the automobile through an end gusset 45 (47, 48). The end gusset 45 (47, 48) may be designed to define a closed section in cooperation with the rear kick-up portion 3, or to extend laterally outward so as to be connected to a front end region of a rear frame 17. The underbody structure of the present invention can prevent or suppress a rearward movement of each rear end of the floor frames during a head-on collision.

Abstract: An automotive vehicle has a rear header disposed at a rear end of the roof and above a rear seat. For example, in the event where the automotive vehicle is about to roll, the seat back of the rear seat is leaned forwards and the upper end portion of the seat back is leaned forwards, thereby forcibly repositioning the head of the rear passenger seated on the rear seat to the position remoter from the back window panel.

Abstract: An automobile rear body structure includes a roof panel, for forming an upper surface of a roof portion of a vehicle body, which is provided with an integrally formed downwardly extending portion to form an outer surface of a rear pillar at a rear side portion thereof. The rear body structure also includes a rear fender panel joined to a lower end of the downwardly extending portion for forming an outer surface of a rear side wall, a quarter panel located inside the rear fender panel, and a reinforcement member for connecting the rear fender panel and the quarter panel at a location near a lower end of the rear pillar. The reinforcement member may be formed by bending the rear fender panel inwardly from a joint between the rear fender panel and the downwardly extending portion of the roof panel. Alternatively, the reinforcement member may be formed of a separate reinforcement element.

Abstract: A front structure of a vehicle body includes a front frame which extends in the longitudinal direction of the vehicle body and is formed of an outer frame and an inner frame connected together to form a closed cross section. A dahsboard lower panel is disposed near the rear edge of the front frame to vertically extend, and a front floor extends rearward from the lower edge of the dashboard lower panel. A side sill is disposed on one side of the front floor at a height lower than the front frame, and a floor frame is disposed on the inner side of the side sill at a height lower than the front frame. The rear end portion of the front frame is connected to the side sill by way of a frame member and to the front end portion of the floor frame by way of another frame member.
