ABSTRACT:
In a vehicle subflame including a pair of longitudinal members extending in parallel with each other along a longitudinal direction of a vehicle body, and lateral members extending across the longitudinal members, one of the lateral members is joined to said longitudinal members via a pair of leg sections which extend upright from the longitudinal member, and each of said leg sections is provided with a bearing portion for pivotably supporting an inner end of one of the lower arms of said wheel suspension system. Therefore, the load from the lower suspension arms can be supported by beating portions which are provided directly on the lateral member, and can be evenly transmitted to the lateral member. When the lateral member is provided with a Z-shaped cross section, the vertical and lateral loads can be supported with high rigidity and mechanical strength while the energy of a longitudinal impact can be favorably absorbed by well controlled deformation of the lateral member.
