A synchronization mechanism of a clutch mechanism includes a drive side contact member and a driven side contact member provided on a drive side clutch member and a driven side clutch member of a clutch mechanism at positions radially inwardly of a drive side clutch portion and a driven side clutch portion, respectively. The driven side contact member does not contact the drive side contact member when the driven side clutch member is in a disengaging position. As the driven side clutch member moves from the disengaging position to an engaging position, the driven side contact member contacts the drive side contact member, so that the rotation of the drive side clutch member is transmitted to the driven side clutch member through frictional contact between the driven side contact member and the drive side contact member before the driven side clutch member reaches the engaging position. |
