Abstract
A rotational force transmission device includes a transmission mechanism disposed on an input gear, and a ratchet member disposed on an output gear. The transmission mechanism includes a first sleeve having a first interlocker, a second sleeve having a second interlocker that engages with the first interlocker with a rotation clearance in the circumferential direction, and a coil spring disposed between the first and second sleeves. When a drive source is stopped, the second sleeve can idly rotate within the rotation clearance between the first and second interlockers. The first sleeve has a first retainer, and the second sleeve has a second retainer engaging with the first retainer in the axial direction. The first sleeve, the second sleeve, and an urging member are unitized by the engagement of the first and second retainers.
