Abstract
A manufacturing method and device for a drive plate that make it possible to obtain well-tensioned teeth at a ring gear portion while extending the life of a shaping die. A preferred embodiment provides a manufacturing device including: a compression punch that compresses a side wall portion of a raw material in an axial direction, the 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 compression die disposed to face the compression punch in the axial direction and having a toothed shape formed on an inner peripheral surface. The compression punch contacts the compression die, and thereafter the compression die is pushed by the compression punch to form a toothed shape on the side wall portion while moving in the axial direction.
