PROBLEM TO BE SOLVED: To improve the rigidity of a front part cross member having a curved part, while minimizing an increase in weight of a rear sub-frame. SOLUTION: There is a possibility of deformation of the front cross member 13 when a large load is inputted from a suspension arm mounting part 16a since the curved part 13a is formed in the front cross member 13 of the rear sub-frame 12 to avoid interference with a driving force input part 30a in which a driving force is inputted from a propeller shaft to a rear differential gear 30. However, the vicinity of the suspension arm mounting part 16a and a mount member 32 for supporting a front part of the rear differential gear 30 in the vicinity of the curved part of the front cross member 13 are connected by a connection member 37, and thereby the front cross member 13 is reinforced by the connection member 37 to prevent the deformation and the increase in the weight of the front cross member 13 can be minimized.
