Abstract
A front-lower arm portion is disposed in the forward direction of a vehicle, while a rear-lower arm portion is disposed in the rearward direction of the vehicle. The rear-lower arm portion is formed of a material having greater tensile strength and compressive strength than that of the front-lower arm portion. A rear end portion of the front-lower arm portion is overlaid with a front end portion of the rear-lower arm portion, thereby securing both end portions together by means of a rivet.
