A starting apparatus (1) includes a drive motor (80) and a reduction gear (10) having a planetary gear (12) for starting an engine by the drive motor (80) via the reduction gear (10). An internal gear (14, 64, 649) of the reduction gear (10) includes a locking projection (143, 643) projecting in an axial direction. A rotation restricting member (18, 68) is formed with a guide groove (181, 481, 683) in which the locking projection (143, 643) is loosely received and guided in a circumferential direction. A shock absorbing member (15, 25, 35, 65) is held in the guide groove (181, 481, 683) in a state of being elastically in close contact with the locking projection (143, 643) in the circumferential direction. Thus, shock load to the internal gear (14, 64, 649) is alleviated from the start. <IMAGE> |
