Abstract
A die apparatus includes a stationary die including a guide bushing, a movable die including a guide post that reciprocates inside the guide bushing, a ball retainer disposed between an inner surface of the guide bushing and an outer surface of the guide post to guide reciprocation of the guide post, and a restriction member coupled to the guide post. The restriction member faces the ball retainer in an axial direction of the ball retainer to restrict separation of the ball retainer from the guide bushing. A distance between the guide bushing and the restriction member in the axial direction when the movable die is located at a top dead center is shorter than a length of the ball retainer in the axial direction.
