SUSPENSION ARM MOUNTING STRUCTURE

PROBLEM TO BE SOLVED: To eliminate the need for shifting a rear side body structure backward by reducing the displacement of a suspension arm 1 at its rear end when displaced backward by collision force to make it hardly interfere with the body structure at the rear side. SOLUTION: When vehicle collision force is applied at the front side of a vehicle to make the suspension arm 1 reduce a gap between body mounting points and move back after rupturing an a circular elastic body 8c of an elastic bush 8, a lower side stopper portion 11 has collision contact with an outer cylinder 8a of the elastic bush 8 to prevent the suspension arm 1 from moving farther back and cause the collision force to act on the suspension arm 1. A rotating moment using a collision contact area between the lower side stopper 11 and the outer cylinder 8a as a supporting point gives mountain-form deformation to a pin 9 to be directed downward to the vehicle. Consequently, the interference of the pin 9 with the body structure such as a dash lower portion 10 at the rear side of the suspension arm 1 is prevented.
