Abstract: A thrust type one-way roller clutch includes a means to assure that the centrifugal force of rotation does not destabilize the ready position of the rollers. The cam ramp surfaces are angularly offset from a radial line in a direction opposite to the allowed direction of relative race rotation. The energizing springs bias the rollers toward a ready position of light engagement with the cam ramp surfaces, thus maintaining the rollers with their individual axes similarly angularly offset. As a consequence, the centrifugal force of rotation will cause the rollers to move in a direction toward ready position only.
