Abstract:
[Problem] To provide the structure of a vehicle component which achieves weight reduction, has high bonding strength and high rigidity against torsional force, tensile force, bending force, or compressive force from all directions, and has manufacturing and cost advantages. [Solution] A vehicle component has a configuration such that an intermediate member (11) produced from a steel plate is provided between an aluminum die-cast trailing arm (1) and a torsion beam (2) produced from a steel plate, one end of the intermediate member (11) is bonded to the torsion beam (2) by welding, and the other end (11a) is integrally insert-cast when the trailing arm (1) is die-cast molded, the vehicle component being characterized in that the intermediate member (11) is molded such that one end is in internal or external contact with an end of the tubular torsion beam (2), and an insert-cast portion (12) comprises a linear tube section (11d) extending parallel to the axis of the intermediate member (11) and a stepped section (11e) formed at at least an end (11b) of the linear tube section (11d).
