<P>PROBLEM TO BE SOLVED: To provide a coupling arm for a vehicle, which is lightweight, has a strength that withstands both tensile force and compressive force, is easy and cost effective to manufacture, and is formed from a highly reliable composite material. <P>SOLUTION: An embossed section 13 is formed which bulges toward the inner direction in a framework plate 7 formed from at least a pair of thin metallic plates arranged facing one another, and due to a concave section 18 formed on the outside surface of an intermediate member 8 and fitted to the embossed section 13, when twisting force, tensile force or compressive force acts on the coupling arm for a vehicle from two shaft members J1, J2, the framework plate 7 counteracts tensile force, the resin intermediate member 8 and an external plate member 9 counteract compressive force, and mainly the intermediate member 8 and the framework plate 7 counteract twisting force, and thus strength for withstanding each of the forces is exerted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
