Abstract
PURPOSE: To reduce friction and noise by making the eccentric moving part of an intermediate side rotor adjustable in the eccentric quantity, and allowing only ratchet claws in a drive territory to mesh with rotor members on the intermediate side and the output side. CONSTITUTION: When a hand operated lever 51 is operated, an eccentric quantity adjusting mechanism 49 constituted of a reel 52, a wire 53, and a lever 42 is operated, and the lever 42 is rotated by the wire 53. Hereby, a moving body 31 is pushed up in the circular recessed part 41 of a guide disc 40, and an intermediate side rotor 30 is made eccentric against a hollow cylindrical case 12 and an output side ratchet 27 according to setting of the eccentric quantity adjusting mechanism 49. Hereby, only drive input side ratchet claws 13A-13D and intermediate transmitting ratchet claws 23A-23D of a second shifting part in drive territories A, A' mesh with an input transmitting side ratchet gear 19 and an output side ratchet gear 27, and the other ratchet claws 13, 23 are regulated by stoppers 18, 26 not to mesh with the gears 19, 27. In this way, friction and noise can be reduced.
