Abstract
In an automotive subframe having a rectangular annular shape as seen in plan view, the longitudinal members have closed cross sections, but the lateral members open cross sections and are provided with open parts adapted to receive a flange projecting from the fuel tank. Because the lateral members have open cross sections, the subframe is capable of undergoing a twisting deformation relatively easily, and the sloshing movement of the fuel inside the fuel tank would not be directly transmitted to the vehicle body. Because the longitudinal members have closed cross sections, and therefore have a relatively high rigidity, the wheel suspension system can be securely supported without creating any possibility of changes in the wheel alignment. Furthermore, the open part of the lateral subframe member can conveniently receive the flange of the fuel tank, and it is possible to maximize the capacity of the fuel tank without causing any interference between the fuel tank and the lateral member.
