However, in such a conventional fuel tank mounting structure for a vehicle, a cross member is added for the purpose of protecting the fuel tank.
The fuel tank had a structure (body and rigid body) that was fixed to the body side parts on the floor. For this reason, although it contributes to the improvement of vehicle body rigidity, it does not share parts with chassis parts, etc.
The fuel tank does not move independently in the direction opposite to the force-applying side in the case of a collision in which the work of assembling the fuel tank, which raises the cost, occurs and the workability of vehicle assembly is poor. However, there is a problem in that it is difficult to obtain the energy absorption stroke of the vehicle body while being dominated by the deformation.

First, the structure will be described. A rear suspension frame 2 for mounting a rear suspension is attached to a rear side member 1 via a bush 3. The rear suspension frame 2 has a shape surrounding a fuel tank 4 from the periphery. ing. The fuel tank 4 is fixed to the rear suspension frame 2, and the rear suspension frame 2 contacts the vertical wall of the rear side member 1 when the rear suspension frame 2 moves in the vehicle front-rear direction at the time of a rear collision (5 in the figure). This contributes to the buckling deformation of the rear suspension frame 2 at the portion shown in the figure at the time of a rear surface collision.
