Time lag is reduced and, at the same time, an increase in the size of the one-way clutch is avoided and the operation of the one-way clutch is stabilized. The one-way clutch (233) includes an outer member (2331), an inner member (2332), a plurality of clutch lugs (233F), a plurality of springs (238), and a plurality of pins (237). The clutch teeth (233C) are provided on one of the inner peripheral portion (233B) of the outer member and the outer peripheral portion (233D) of the inner member. The clutch lugs are provided on the other of the inner peripheral portion and the outer peripheral portion. The springs are provided on the other of the inner peripheral portion and the outer peripheral portion. The number of clutch lugs is an even number not smaller than 4 (four). The number of clutch teeth is an even number that is not a multiple of the number of the clutch lugs. The number of springs is half the number of clutch lugs. Each spring is capable of exerting a biasing force on two of the clutch lugs that are adjacent as determined along the circumferential direction. Each pin is in contact with one of the springs.
