Abstract:

Disclosed is a dog clutch (10) that transmits driving force from a driving-side rotating body (16) to a driven-side rotating body (23). In the bottom face (32) of recessed parts (17) formed in the driving-side rotating body (16) there is a strip-shaped island part (33) protruding from the bottom face (32) in the circumferential direction, and there are groove parts (34) between the island part (33) and torque-receiving surfaces (31). The groove parts (34) and the bottom face (32) are formed by means of a forging mold (50), and their surfaces are forged mill scale. The island parts (33) have a cut surface (37), which is formed by cutting the top part of the islands after they have been formed by the forging mold (50), and which receives the tip surface of a protruding part (24). The groove parts (34) are formed so as to be deeper than the bottom face (32), and the cut surface (37) is formed so as to be shallower than the bottom face (32).
