Zusammenfassung:A press device includes: a first die having a shape of an elliptical cylinder; a second die having a first recess that forms a part of an elliptical-cylindrical space configured to arrange the first die therein; a third die having a second recess to be combined with the first recess to form the elliptical-cylindrical space; a first press mechanism that inserts the first die along a radial direction of the first die to the first recess of the second die over which the flat metal stock is placed so as to press the metal stock; and a second press mechanism that moves the third die relative to the first die inserted to the first recess so as to confine the first die and the metal stock in the elliptical-cylindrical space formed by the first recess and the second recess.
