Abstract: A vehicle rear structure includes a side sill joined to a rear frame via an outrigger, a sub-frame mounted on the rear frame from below, and a fuel tank mounted on the sub-frame. The sub-frame is provided with a load transmitting member that opposes the outrigger. An impact load applied to the sub-frame is transmitted to the outrigger via the load transmitting member. The transmitted impact load is distributed to the two components, the rear frame (specifically, front frame section) and the side sill via the outrigger.

Abstract: A vehicle body rear part structure improved against rear-side collisions is disclosed. The rear part of a vehicle body includes left and right rear side frames; a front cross member and a rear cross member, both extending between the left and right rear side frames; and a bar and a bracket. The rear cross member has arm support parts for supporting lower arms of left and right rear suspensions on a center part which is lower than lateral ends of the vehicle body. The bar is curved in a convex manner toward the bottom of the vehicle body, and the bar connects center parts of the front and rear cross members together. The bracket mounts a rear end of the bar to the rear cross member while enclosing the rear end from the bottom of the vehicle body.

Abstract: A rear frame structure for a vehicle is disclosed, wherein an impact load can be satisfactorily absorbed in the case of a collision with a rear surface of the vehicle. The rear frame structure includes a pipe-shaped impact-absorbing member located between left and right rear frames. The impact-absorbing member has a center pipe that has a V shape in plan view, formed so as to protrude backward. The impact-absorbing member has left- and right-side pipes extending from the center pipe linearly upwardly to left and right end pipes. The impact load applied to the center pipe causes the left- and right-side pipes to undergo compressive deformation in their axial longitudinal directions as well as bending deformation towards the front of the vehicle body, whereby the impact load is absorbed.
