The present invention has an object to provide a manufacturing method for a toothed part that allows manufacture of a toothed part in a desired shape using shaping dies with a simple structure, and a manufacturing device for the toothed part. Thus, an aspect of the present invention provides 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 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. |
