Claims

[Scope of utility model registration request]

A change drum and a shift shaft are provided in parallel, a plurality of drum pins are provided at an end of the change drum in parallel to each other at intervals in the circumferential direction, and a pole is supported on a shift plate integrally formed with the shift shaft, In a gear transmission mechanism in which a pawl is engaged with the above-mentioned pin and a change drum is rotated by the rocking of the plate and the pawl, the rocking at the time of upshifting and the rocking at the time of downshifting occur when viewed from the center line of the drum. The plates are arranged symmetrically with respect to the center line, and one overshift stopper is formed on the plate that protrudes toward the drum side, so that the stopper can stop each pin at both the end of an upshift and the end of a downshift. A gear transmission mechanism characterized in that a pin is positioned on a circumference that passes through and locks a pin.
