A manufacturing method for a toothed member that uses a compression punch that is driven by a first slide shaft driven to be ascended and descended by a first slide shaft drive mechanism and that compresses a side wall portion of a cup-shaped raw material in an axial direction of the cup-shaped raw material, the cup-shaped raw material including a bottom surface portion and the side wall portion which is cylindrical and provided to extend upright from an outer peripheral end portion of the bottom surface portion, a restraint punch (14, 96) that is driven by a second slide shaft driven to be ascended and descended by a second slide shaft drive mechanism and that restrains a first surface of the bottom surface portion located on a side of an opening end of the cup-shaped raw material, and a pressure receiving member that restrains a second surface of the bottom surface portion located on the opposite side of the bottom surface portion from the first surface, the manufacturing method for a toothed member that includes a thickened tooth shaping process in which the first slide shaft is driven to be ascended and descended by the first slide shaft drive mechanism after restraining the first surface and the second surface by the restraint punch (14, 96) and the pressure receiving member by driving the second slide shaft to be ascended and descended by the second slide shaft drive mechanism, and a toothed shape is formed on the side wall portion while making a thickness of the side wall portion larger than a thickness of the bottom surface portion by relatively moving the compression punch with respect to the restraint punch (14, 96) and the pressure receiving member in the axial direction from the side of the opening end of the cup-shaped raw material toward the bottom surface portion, the manufacturing method for a toothed member being characterized in that the thickened tooth shaping process includes driving the second slide shaft to be ascended and descended by the second slide shaft drive mechanism, applying to the restraint punch (14, 96) such a load that allows the restraint punch (14, 96) to keep restraining the first surface and the second surface, and preventing trapping of a material in a portion linking the side wall portion and the first surface, the second slide shaft being disposed inside the first slide shaft, the restraint punch including a restraint surface that restrains a first surface of the bottom surface portion and an outer peripheral surface that is provided to extend upright from an outer peripheral end portion of the restraint surface so as to form an inner peripheral surface of the side wall portion of the raw material, and the restraint punch (14, 96) including a first restraint punch, a second restraint punch, and a toothed punch or a round punch, wherein the first restraint punch includes a projecting portion, a first distal-end surface and a second distal-end surface, wherein the toothed punch is provided with a distal-end surface along the outer peripheral of the toothed punch and facing the second restraint punch for forming the side wall portion, wherein the round punch is a punch in which an outer peripheral surface is smooth and has the same diameter over the entire periphery.
