PROBLEM TO BE SOLVED: To ensure good shock absorbing performance of a vehicle frame by providing, in a suspension arm support of a suspension cross member, a fragile portion that is made weaker than other portions in the circumferential direction of a support bushing installed in the suspension arm and causing this weak part to fracture during collisions, particularly in frontal crashes, to allow the suspension cross member to separate from the vehicle frame. SOLUTION: This vehicle suspension support structure is built by fixing one end of a suspension arm 8 together with a suspension cross member 3 in a direction perpendicular to a vehicle frame member. A fragile portion 26b that is made weaker than other portions in the circumferential direction of a support bushing 7 installed in the suspension arm 8 is provided in a suspension arm support 5 of the suspension cross member 3.
