Abstract
A manufacturing method for a toothed part including a bottom surface portion and a side wall portion provided to extend upright from an outer peripheral end portion of the bottom surface portion, the side wall portion being fanned with teeth. The manufacturing method includes a half drawing process of performing draw shaping on a material having a disk shape to form the bottom surface portion and the side wall portion, an inside diameter of which becomes larger in a direction away from the bottom surface portion; and a tooth shaping process of forming the teeth in the side wall portion.

A manufacturing method for a toothed part including a bottom surface portion and a side wall portion provided to extend upright from an outer peripheral end portion of the bottom surface portion, the side wall portion being formed with teeth, the manufacturing method for a toothed part being comprising:
- a half drawing process of performing draw shaping on a material having a disk shape to form the bottom surface portion and the side wall portion, an inside diameter of which becomes larger in a direction away from the bottom surface portion;
- and
- a tooth shaping process of forming the teeth in the side wall portion.
A manufacturing device for a toothed part including a bottom surface portion and a side wall portion provided to extend upright from an outer peripheral end portion of the bottom surface portion, the side wall portion being formed with teeth, the manufacturing device for a toothed part being comprising:
- a toothed punch, on an outer peripheral surface of which teeth are formed;
- a drawing die including a draw shaping hole for insertion of the toothed punch;
- and
- a toothed die including a tooth shaping hole for insertion of the toothed punch, wherein
- the toothed punch is inserted into the draw shaping hole and relatively moved with respect to the drawing die to perform draw shaping on a material having a disk shape in order to form the bottom surface portion and the side wall portion, an inside diameter of which becomes larger in a direction away from the bottom surface portion, and
- the toothed punch is inserted into the tooth shaping hole and relatively moved with respect to the toothed die to form the teeth in the side wall portion.
