    摘要： 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.

    摘要： A hub for a bicycle includes a shaft (12), a hub body (40), a ratchet wheel (43), a drive seat (10), a support ring (15), a rotation ring (21), a plurality of pawl members (22), a stop bushing (121), a limit ring (30) and a damper (33). Thus, when the drive seat is rotated backward by the pedal, each of the pawl members is retracted into the respective receiving slot (212) of the rotation ring to disengage the oneway ratchet teeth (43) of the ratchet wheel, so that each of the pawl members is spaced from and will not touch the ratchet wheel when the pedal is driven backward to prevent from producing a noise when the pedal is driven backward.

    摘要： A hub for a bicycle includes a shaft (12), a hub body (10), a ratchet wheel (13), a damper (20), a drive seat (30), a plurality of pawl members (32), and a plurality of elastic plates (33). Thus, when the pedal is driven backward (and the drive seat is rotated backward), each of the pawl members is fully hidden in the respective receiving slot (313) of the support base, and the locking detent (320) of each of the pawl members is detached from the oneway ratchet teeth (131) of the ratchet wheel constantly, so that each of the pawl members will not touch the ratchet wheel when the pedal is driven backward to prevent from incurring a noise when the pedal is driven backward.
