In a vehicle frame structure, an upper edge of a frame member is fixed to a lower face of a substantially flat panel, and a bottom wall of an upper stiffener fixed to an inner face of an upper part of a curved portion of the frame member and a bottom wall of a lower stiffener fixed to an outer face of a lower part of a region between two inflection points of the curved portion are arranged in an X shape relative to a top point of the curved portion. Therefore, when a compressive load in the longitudinal direction acts on the frame member, the curved portion of the frame member is effectively prevented from bending by counterbalancing the upward load acting on the lower stiffener bottom wall with the downward load acting on the upper stiffener bottom wall. Moreover, the upper stiffener and the lower stiffener are U-shaped cross-section members that can be formed by bent sheet metal, and thereby minimize any increase in weight due to installation of the stiffeners.

Vehicle frame structure

A vehicle body rear part structure includes a rectangular support frame carrying thereon a cylindrical fuel tank and attached to left and right rear frames from below via left and right front brackets and left and right rear brackets so as to define therebetween a pair of laterally spaced openings generally corresponding in position to the axis of the fuel tank and receiving therein a pipe system of the fuel tank.

Vehicle body rear part structure

A vehicle body rear part structure includes left and right rear frames extending longitudinally of the vehicle body, a plurality of parallel spaced cylindrical fuel tanks disposed horizontally between the left and right rear frames with the axes of the fuel tanks extending normal to the left and right rear frames and disposed below the center of a height of the rear frames, and a cross member disposed between two adjacent ones of the fuel tanks and extending between the left and right rear frames. The cross member reinforces the rear frames to such an extent that fuel tanks of larger capacity can be carried on the vehicle body rear part structure.
