Abstract

A method for manufacturing a vehicle body member from a joined sheet. The joined sheet is press formed into a vehicle body member with a predetermined shape by: welding a second sheet material to a first sheet material at a plurality of points including a first joint and a second joint separated from each other; press forming the joined sheet so that a ridge crossing an imaginary line segment connecting the first joint and the second joint is formed in a portion where the first sheet material overlaps the second sheet material; and before the joining step, forming a displacement facilitating portion, which facilitates displacement of the second sheet material relative to the first sheet material in a longitudinal direction of the imaginary line segment, in a portion corresponding to between the first joint and the second joint in the second sheet material.
