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.

Abstract: A vehicle frame includes an elongated main body member, a reinforcing member along the main body member, and an adhesive layer that joins the main body member and the reinforcing member. The main body member includes a main body first wall portion and two main body side wall portions. The reinforcing member includes a reinforcing first wall portion and two reinforcing side wall portions. The adhesive layer is formed such that a thickness between the main body side wall portion and the reinforcing side wall portion at a reinforcing side end portion is larger than a thickness between the main body first wall portion and the reinforcing first wall portion.
