Suspension member and method for manufacturing same

Abstract

A suspension member and a method for manufacturing the same are provided by which it is possible to manufacture the suspension member at a low cost without decreasing rigidity thereof while also suppressing strain at joining portions. The present invention is a method for manufacturing a suspension member (100) provided with: a pair of side members (40), and a cross member (10) linking the pair of side members and including an upper member (11) and a lower member (21) extending in a lateral direction of a vehicle and provided with base portions (12 and 22) and raised portions (15, 16, 25, and 26). The method includes: an assembly step (ST1) in which the cross member is formed by the upper member and the lower member and is assembled into a state where the side members are inserted from the outside into an internal space (S) formed therein by the upper member and the lower member; a first joining (ST2) in which the upper member and the lower member are joined together; and a second joining step (ST3 and ST4) in which the side members and the cross member overlapping each other in the internal space are joined together.
