Abstract
An arm member is used as, for example, a suspension arm of an automobile. The arm member comprises a main body made of a pipe member and a coupling member having a connecting portion. The pipe member is made of aluminum or its alloy. The coupling member is made of aluminum and includes a bushing mounting portion for mounting a vibroisolating bushing. The thickness of the peripheral wall of the end portion of the main body is increased in thickness to have a thickness thicker than that of the other portion of the main body. The connecting portion is abutted to the peripheral wall of the end portion to form an abutted portion, and connected thereto at the abutted portion. Thus, the coupling member is coupled to the main body.
