Claim 8:
9. A method for producing a pressure plate including a body, a flange extending radially outward from an outer circumferential edge of the body, a plurality of pressure-side fitting teeth projecting from a front surface of the flange, holding output-side rotating plates, and being arranged in a circumferential direction, and a flange-side recessed portion located in a back surface of the flange, the method comprising:
preparing a mold including a fixed mold and a movable mold allowed to approach, or to be separated from, the fixed mold;
causing the movable mold to approach the fixed mold to close the mold;
filling a molding space formed by the movable mold and the fixed mold with a metal material;
cooling and solidifying the metal material to form the pressure plate by molding and then separating the movable mold from the fixed mold to open the mold; and
detaching the pressure plate from the movable mold by pushing a core pin against a portion of the back surface of the flange of the pressure plate fixed to the movable mold that overlaps one of the pressure-side fitting teeth as seen in a mold moving direction that is a direction in which the movable mold is moved with respect to the fixed mold.
