  • Member for arm
    Patent number: 6298962
    Abstract: There is disclosed a member for use with an arm that is used as an automobile suspension arm, for example. The member comprises a rodlike body and bushing-mounting portions formed at both ends of the rodlike body. The rodlike body consists of a hollow tube fabricated by extruding an aluminum material into a circular cross section. The bushing-mounting portions are formed by welding bushing-mounting members to both ends of the rodlike body. Each bushing-mounting member has a hole in which a bushing is mounted with a press fit. The curved wall of the rodlike body is recessed at the longitudinal center of the rodlike body. When an automobile having the aforementioned member collides, an axial compressive load is applied to the rodlike body. The rodlike body buckles at the recessed portion. This mitigates the impact in the collision.
