The first type planetary gears (33X) and the second type planetary gears (33Y) are different from each other in phase of gear teeth (35a) of the second gear portion (35) with respect to gear teeth (34a) of the first gear portion (34). The first type planetary gears (33X) and the second type planetary gears (33Y) are arranged alternately in a circumferential direction.",
