Abstract

A method for manufacturing a vehicle structure member by using a hollow extruded material that has a pair of side plates and a plurality of connecting plates connecting the side plates together and that has a quadrilateral closed section and a longitudinal shape, such that a width dimension of the vehicle structure member, which is a distance between the side plates, varies in a longitudinal direction of the vehicle structure member, the method including: an extrusion molding step of producing the hollow extruded material with the connecting plates each having a bent shape by extrusion molding; and a widening step of increasing the width dimension by increasing the distance between the side plates partially in the longitudinal direction so as to flatten the connecting plates having the bent shape.
