摘要：PURPOSE:To certainly switch rotation in simple structure of a compact shape by incorporating, between a cam surface and an outer diameter surface, an engaging piece engaged with the cam surface and the outer diameter surface. respectively, and an elastic member for pressing the engaging piece against the cam surface and the outer diameter surface. CONSTITUTION:At the inner diameter surface of a second drive disk 8, a plurality of notches 12 each incorporating an engaging roller 11 are formed at predetermined intervals in the inner circumferential direction. The inner circumferential surface is adapted to be cam surfaces 13 each forming a wedge-shape space in the circumferential direction between the inner circumferential surface and the outer peripheral surface 5a of a bearing 5. An interval between the cam surface 13 and the outer peripheral surface 5a of the bearing 5 is smaller than a diameter of the roller 11 at one end of the notch 12 while larger at the other end. A spring 15 having an S-shaped cross section is inserted into a pocket 14 formed continuously to the notch 12. The resilient force of the spring 15 is exerted on the roller 11 in such a manner as to separate the roller 11 from the pocket 14. Consequently, the roller 11 moved in the wide portion of the notch 12 is returned to the position where it is engaged with the cam surface 13 and the outer peripheral surface 5a of the bearing 5.
