Zusammenfassung:A rotation transmission device transmits the rotation force to an output shaft. The rotation transmission device includes a rotation body and a buffer mechanism. The rotation body includes a plurality of engagement portions. The buffer mechanism includes an elastic member and a transmission plate. The elastic member includes multiple pairs of damper portions. Each pair of damper portions is arranged to contact two side surfaces of one of the engagement portions. The transmission plate includes an output connection portion, a planar portion, and a plurality of engagement pieces. The output connection portion is connected to the output shaft. The engagement pieces are bent from the planar portion to project in an axial direction. Each of the engagement pieces cooperate with one of the engagement portions to sandwich each of the damper portions in the circumferential direction.
