A pulley has a hub fixed to a rotating shaft. An outer wheel is disposed on the outer periphery of the hub and around which a belt is suspended, and a unidirectional clutch is interposed between the hub and the outer wheel. A cam face for forming a wedged space of the unidirectional clutch is formed at the inside of the pulley, whereby the unidirectional clutch is switched between a free state and a locked state through the rotational variation of the hub which rotates integrally with the rotating shaft to reduce the transmission of the rotational variation from the hub to the outer wheel. Further, the unidirectional clutch can operate stably without suffering the effect of the rotational centrifugal force.
