A simple closed end structure from the side plate material also has a challenge to enable molding with good dimensional accuracy. In the first step of the press forming, the shape forming the curvature required in the closed-end surface shape in the machine direction and the transverse direction relative to the work piece (1). In the following second step, with respect to a material to be processed (1) molded in the first step, the bottom part (2), (3) the board by sandwiching the punch 15 and the pad 16 from the thickness direction, the side wall of the right and left the parts 4, 5, 6 forming a bend in a direction to approach. Next, in the third step, the second bottom portion of the material to be processed (1) molded in step (2), (3) the pad 16 in a state placed on a pair of flange portions (7), (8 ) the face, the die cavity of the right and left the same room shape, and the end of the closed end surface by a press-side press-fitted portion side wall shape of the bottom support parts of the support surface and a pair of the pressing cam 26 in the pad 16 together forming compartments. Then, the pressing down toward the pair of flange portions (7), the cavity of the second punch pressure bottom 31, a pair of flange portions (7), (8) in the 21 disposed above the (8).
