A stopper member that engages in the circumferential direction and allows the second protrusion and the bottom surface of the gap to engage in one side in the axial direction, and regulates the movement of the second protrusion in the other axial direction to the first protrusion. Since the connecting structure is such that the first rotating member is connected so that the thrust force of the second rotating member is received by the stopper member, the first rotating member can be connected with a larger diameter or a smaller diameter than the second rotating member. Therefore, the first rotating member and the second rotating member
The rotating member has an effect that a high degree of freedom in design can be obtained without giving mutual dimensional restrictions.

Since the protrusion is formed, the second protrusion is engaged with the first protrusion formed on the output shaft, and the output gear is provided on the outer periphery of the output shaft, the ring gear and the output gear are arranged close to each other. The axial dimension can be shortened. Moreover, in the output shaft, since the machining direction of the output gear and the first protrusion is substantially perpendicular, there is no axial gap between the output gear and the first protrusion. Since it is not necessary to provide it, the size in the axial direction can be shortened, and the effect of high design freedom and the effect of shortening the axial size can be obtained together.
