The rotation relay member includes a housing and a cylindrical one-way clutch. A contact portion between the driving rotation member and the shaft is configured to rotate the driving rotation member and the shaft to transmit the driving force to an inner peripheral side of the cylindrical one-way clutch via the shaft. The driving rotation member includes a boss projected toward the holder and rotatably held in the holder. A portion of the shaft to support the driving rotation member and an inner wall surface of a through hole of the driving rotation member are shaped to rotate the shaft and the driving rotation member. together.
