Abstract
To increase strength without any weight increase due to a thickness increase and without causing the machining problem in half-blanking, an external gear and an internal gear are ring-shaped gears, and external teeth and internal teeth each have a tooth width substantially corresponding to the thickness of an outer circumferential surface of the external gear or an inner circumferential surface of the internal gear. The external gear and the internal gear are ring-shaped gears, that is, each can be formed through the punching of a plate, and strength resulting from the engagement of the external teeth and the internal teeth corresponds to strength resulting from the thickness of the material plates forming the external gear and the internal gear. Accordingly, the external teeth and the internal teeth can have a wider tooth width, achieving higher strength than when half-blanking is used.
