ABSTRACT:
A driving gear for a bicycle is provided which comprises a gear body provided with a large number of teeth and a support member supporting the gear body. Between the gear body and the support member there is provided a driving transmission for transmitting a driving force from one of the gear body and support member to the other. A gap is provided at the driving force transmission through which the gear body and support member are rotatable relative to each other by a predetermined angle. At a location shifted from the driving force transmission there is provided an elastic member which compensates the gap and is elastically deformed when the gear body and support member rotate relative to each other so as to absorb the gap, thereby enabling the driving force to be transmitted from the driving force transmission.
