Abstract
A pair of rear wheel suspension assemblies are attached to arm brackets provided on a fuel tank which is in turn mounted on a lower surface of a vehicle body by means of mount brackets likewise attached to the fuel tank. An inner frame is incorporated inside the fuel tank. To prevent any deformation of the fuel tank when excessive load is applied to the suspension assemblies, the mount brackets and the arm brackets are made less rigid and provided with less mechanical strength than the parts of the fuel tank at which these brackets are attached. Thus, the fuel tank in effect serves as a subframe so that the rear chassis system can better ensure sufficient mechanical strength and rigidity, and can be easily mounted on a vehicle body without sacrificing the capacity of the fuel tank and without increasing the weight of the chassis structure.
