Abstract
Method of manufacturing a vehicular arm component having a particular torsional rigidity and a sufficient tensile strength. Method of manufacturing a vehicular arm componenthaving a hollow shape in open cross-section by subjecting workpiece W, which is a flat plate, extending in an XY plane to pressing in stages such that two side surfaces W, Wof the workpiece in an XZ plane formed by the X direction and a Z direction face one another across a gap G, the method including a restriking process in which a protrusiondisposed on a restriking dieto be extended in the X direction is arranged in the gap between the two side surfaces facing one another and the two side surfaces are brought into contact with the protrusion such that the workpiece is pressed from an outer periphery to an inner periphery.
