The retainer includes a plurality of holding portions disposed among the rollers, and shaft portions that protrude from the holding portions toward the rollers. The cam surface is an oblique surface on the inner peripheral surface of the outer ring and arranged to contact the outer peripheral surface of the rollers. The spring members are disposed on the outer peripheral side of the shaft portions and urge the rollers to frictionally engage the cam surface.
