ABSTRACT:
A multi-gear-speed transmission includes cam rods in sliding contact with an inner peripheral surface of an inner cavity of a gear shaft; pin members inserted in pin holes bored in the gear shaft in the radial directions and which are advanced or retreated by alternatedly making contact with the sliding contact surfaces of the cam rods and cam grooves. Swing claw members are rotatably supported on pivot pins provided in the gear shaft and which are advanced or retracted by the pin members to be engaged with or disengaged from gears (n). The swing claw members and the pivot pins are embedded in recessed parts formed in the outer periphery of the gear shaft, annular bearing collar members externally fitted over the gear shaft are arranged to press the pivot pins from the outer side, and the gears (n) are rotatably borne on the bearing collar members.
