Abstract
The present invention provides a sprag type one-way clutch of disengaging type comprising an outer race having a substantially annular inner peripheral track surface, an inner race spaced apart from the outer race in a radial direction and disposed coaxially with and rotatable relative to the outer race and having a substantially annular outer peripheral track surface, a plurality of sprags disposed between the outer race and the inner race to transmit torque between the inner and outer track surfaces, and a ribbon spring for applying rising moment to the sprags, and wherein an outer diameter side cam surface of the sprag is provided with a mechanism for preventing fluctuation of the sprag during a predetermined number of idle revolutions of the outer race.
