Claims

[Scope of utility model registration request]

In a transmission device configured to sequentially increase or decrease speed from low to high speed by operating the operation pin 36° 37.38 of the speed change sliding body fitted in the cam groove 53a by rotating the speed change cam 53, the speed change is performed. A small-diameter pinion gear 52 is fixed on the camshaft 49, and a rank 50 that is slidable in the front and rear directions of the transmission case is engaged with the pinion gear 52, and the rack is moved back and forth using a push-pull wire from the gear shift lever. A transmission device characterized in that it can be operated by sliding.
