Abstract

PURPOSE: To lessen friction at the time of shifting and to prevent an impulsive sound form occurring by arranging a guide for guiding a ratchet claw so that only the ratchet claw in the drive area engages with a rotating member on the output side at all times when shifting. CONSTITUTION: An input side rotating member 12 rotates by the drive force applied to a crankshaft 5 and a ratchet gear 29 is rotated through a ratchet claw 13 mounted on the member 12. The inclination angle of the ratchet claw 13 is varied by an eccentrical movement of an eccentrical moving body 25 of a manual type eccentricity amount adjusting mechanism and a wheel rotation ratio with respect to the crankshaft 5 is varied to be continuously variable. On this occasion, the ratchet claw 13 is guided by a guide 19 provided on the input side rotating member 12 and only the ratchet claw 13 inside the drive area is engaged with a ratchet gear (output side rotating member) 29, while other ratchet claws 13 are removed from the ratchet gear 29. As a result, friction and impulsive sound occurring at the time of shifting can be prevented.
