輪車におけるチェンジカム駆動機構。By operating the shift pedal, the change cam is rotated through a shift shaft, a fan-shaped cam shift arm, an arcuate rack formed at the tip of the arm, a cam driven gear that meshes with the rack, and a ratchet mechanism, thereby engaging the cam. In a change cam drive mechanism for a motorcycle that operates a gear shift fork that is fitted together to perform a speed change operation, a plate-shaped convex portion is formed on the side of the tip of the fan-shaped cam shift arm, and an arc-shaped convex portion is formed on the inner end surface of the convex portion. A change cam drive mechanism for a motorcycle, characterized in that a rack is formed, and the fan-shaped cam shift arm covers the cam driven gear so that the arcuate rack is engaged at an apogee of the cam driven gear.
