In the press working machine, a first working plate is downwardly moved by a rod of an air cylinder. At this time, the lower end of a lock pin is in contact with a horizontal plane, whereby the first working plate is rotated about a second rotation axis. Thus, a first rotation axis is upwardly rotated about the second rotation axis, to further upwardly move a lower mold base. At this time, a lower mold and an upper mold are already in contact with each other, whereby a high thrust is caused between the molds to enable molding/joining of metal plates or the like. Consequently, it is possible to provide a press working machine which can embody both of a low-thrust/high-speed area and a high-thrust/low-speed area through only a single air cylinder.
