Abstract

PURPOSE: To prevent pulsation of transmission power and metallic noise from occurring on a continuously variable transmission by the feeding action of a ratchet claw engaging with a ratchet gear by providing a cushion on the ratchet claw blade. CONSTITUTION: A plurality of ratchet claws 13 arranged in parallel inside a hollow cylindrical case 12 integrally fixed to a crankshaft 5 with a crank arm are respectively supported by a pivot 16 in a rotationally movable manner and energized inward by a spring 17. A disk shape stationary cam 23 is fixed to the end of a hanger rack 4 integrally formed with a body frame and a ratchet gear 29, which becomes an output side rotational member, is mounted in a rotationally movable manner on the periphery of an eccentric cam 25 provided on the periphery of the stationary cam 23 in a rotationally movable manner. With such a transmission, the ratchet claws 13 are composed of a divided piece 13A including a tooth 14, a divided piece 13B including a receiving face 18, and a divided piece 13C including a tooth 14A and composed of an elastic material such as a rubber sandwiched between the divided pieces 13A, 13B.
