A one-way clutch is composed of a flat pulley having a circular friction surface provided on the outer circumferential surface of the flat pulley to extend circumferentially along the friction surface, a V-grooved pulley combined with the flat pulley to be rotatable relative thereto around the centerline of the friction surface and having an arc-shaped friction surface provided on the outer circumferential surface of the V-grooved pulley radially outwardly of the friction surface to extend circumferentially, an endless flat belt wound between the friction surfaces of the flat pulley and of the V-grooved pulley, and a plate spring for applying initial tension to one span of the flat belt between the pulleys. The one-way clutch has a simple structure obtainable at low cost, need not operate with high precision, and suffers a reduced number of failures resulting from excessively large input torque. In the event of failure, it is sufficient to replace the failed component. Moreover, the maximum transmissible torque can be varied.
