Abstract
A full type one-way clutch includes rollers arranged in a full type state between an outer ring having inclined cam surfaces on the inner peripheral surface thereof and a rotary shaft. A spring biases the rollers in such a direction as to engage the cam surfaces, and the spring is arranged in a groove formed in the inner peripheral surface of the outer ring. By keeping all the rollers in abutment with one another, it is possible to reliably and instantly transmit the biasing force of the spring to all the rollers without reducing the torque-transmitting ability while improving the responsiveness of the clutch.
