Abstract
PURPOSE: To reduce friction, and to prevent the occurrence of impact sound by providing an interlocking means for guiding ratchet claws so that only the ratchet claws within the driving region at the time of eccentricity of an eccentrically moving body are engaged with an output side rotating member. CONSTITUTION: An interlocking pin 25 is engaged with a guide groove 26 as the ratchet claws 19 within the driving region D are tilted to turn an interlocking member 23, so that all the ratchet claws 19 are interlocked to each other for keeping the same inclination. Therefore, at the time of speed change, only the ratchet claws 19 within a driving region D out of the entire ratchet claws 19 engage with the ratchet gear, and the other ratchet claws 19 are rotated in the state they are disconnected from the ratchet gear. Accordingly, the occurrence of friction and impact sound as before caused by frictional movement while the ratchet claws 19 outside the driving region D are moved in contact with a ratchet gear can be prevented as much as possible.
