Abstract
A manufacturing device manufactures a component having a hat-shaped section as a pad and a punch sandwiching a center portion of a metal plate, and a die and a holder sandwiching both side portions of the metal plate are moved relative to each other in the upper-lower direction. The manufacturing device includes the die, the pad provided inside an opening of the die so that the pad is able to move relative to the die, the punch arranged to face the pad in the upper-lower direction, the holder arranged around the punch so as to face the die in the upper-lower direction and be able to move downwardly, and a locking block provided on the holder. The locking block is moved from a non-facing position to a facing position and inserted between the pad and the holder after mold closing and before mold opening.
