<p>Provided is a forced speed changing apparatus of bicycle. The forced speed changing apparatus of bicycle is characterized in that a pressure member is disposed at the pawl controlling ring (15), and a spline groove (27), is formed at an inner circumference of the carrier (20) so that the pressure member is moved by rotation of the carrier (20) so as to press the pawl (12,13) and to release engagement between the pawl (12,13) and the sun gear (23,24). Therefore the function and operation of the forced speed changing apparatus of bicycle can be enhanced.</p> |
