ABSTRACT:
A ratchet gear, particularly for driving hubs of bicycles, having a pawl mounted in a pawl carrier without the use of bolts. The head of the pawl is provided with a securing surface which, even when the pawls occupy the engaged position, is situated opposite an intercepting surface of the pawl carrier, in the peripheral direction about the pivot, so that the partly cylindrical bearing foot of the pawl cannot be moved out of the partly cylindrical bearing bushing to any great extent and it is impossible for the head of the pawl to become jammed between the pawl carrier and the gear carrier.
