Abstract

PURPOSE: To prevent pulsation of transmission force by providing ratchet pawls to be rotatable through a shock absorbing means in a device for continuous variable transmission by feeding action to the ratchet pawls meshed with a ratchet gear. CONSTITUTION: A hollow cylindrical case 12 integral with a crank arm is fixed on a crank shaft 5, plural ratchet pawls 13 are disposed in parallel inside it, they are each rotatably supported by a pivotal shaft 16, and each is energized inward by a spring 17. A circular fixed can 23 is fixed at an end part of a hanger rack 4 integral with a car body frame, and a ratched gear 29 as an output side rotation member is rotatably installed on an outer circumference of an eccentric cam 25 rotatably provided on a circumferential edge of it. In this case, each pivotal shaft 16 is engaged in a slit 13a of each ratchet pawl 13 with play, a coil spring 17A is wound as a shock absorbing means SA1 around a support shaft 16A provided on the back of the ratchet pawl 13, and a base end of the ratchet pawl 13 is energized forward.
