Abstract

PURPOSE: To select conditions for moving a bicycle forward or backward only by providing a ratchet tooth line to be engaged with both first and second ratchet claws, and providing a changing mechanism to selectively set both ratchet claws in a non-actuation condition. CONSTITUTION: As first ratchet claws 13 are set in a non-actuation condition by a changing mechanism C, second ratchet claws 14 only are engaged with a ratchet tooth line 12, and a second ratchet mechanism only functions. In this case, inverse rotation force of a drive body 6 only is transmitted to a hub body, so a bicycle can be moved backward. In the meanwhile, as the second ratchet claws 14 are set in a non-actuation condition, the first ratchet claws 13 only are engaged with the ratchet tooth line 12, and a first ratchet mechanism only functions. Normal rotation force only of the drive body 6 is then transmitted to the hub body 7, so the bicycle can be moved forward.
