大きく確保したことを特徴とするシフト機構。A star-shaped cam body attached to one end of the shift drum and having a positioning notch corresponding to each gear stage, and a neutral positioning notch formed between the first continuous positioning notch and the positioning notch for second gear; In a shift mechanism for a motorcycle transmission comprising a stopper roller that engages with each notch of a molded cam body to hold a shift drum at each gear position and a neutral position, the stopper roller engages with the stopper roller. By setting the contact angle of the positioning notch corresponding to each gear stage to 2θ, the shift angle between the 1st and 2nd stations to 40, and the shift angle between the 2nd and 2nd stations to 4θ + α, the stopper A shift mechanism characterized by ensuring a large contact angle of the neutral positioning notch with respect to the roller.
