<p>PROBLEM TO BE SOLVED: To improve load transmission performance by a coupling member upon head-on collision.SOLUTION: In a vehicle 10 to which a vehicle front lower part structure is applied, the fitting plane 44A of a fitting piece 40 is arranged as inclined to the vehicle front side and the vehicle lower side in the vehicle front/rear direction in a side view. Therefore, when collision load to the vehicle rear side is input to the fitting piece 40 through a coupling member 22, a component force in the direction toward the vehicle lower side acts to the fitting piece 40. Thus, the fitting piece 40 is mainly deformed as bending to the vehicle lower side. Concretely, the fitting piece 40 is deformed to the vehicle lower side so that the angle between a vertical wall 42 and a lateral wall 44 becomes small and the coupling member 22 is displaced to the vehicle rear side and to the vehicle lower side. Therefore, the coupling member 22 is suppressed to displace to the vehicle rear side and to the vehicle upper side, and the coupling member 22 is displaced to a lower arm 16 side. As a result, the coupling member 22 butts the lower arm 16, and the collision load is transmitted to the lower arm 16 by the coupling member 22.</p> |
