Abstract: A press-molding device (80) press molds a bottom portion of a work piece (9) having a closed-end shape between an, inner die (521) inserted into the work piece (9) and an outer die (551) disposed on an outside of the work piece (9). A chuck position switching mechanism (501) grips the work piece (9) so that the work piece (9) can move in an axial direction. An inner die moving mechanism (522) inserts the inner die (521) into the inside end of the work piece (9).
