Claims

[Scope of utility model registration request]

An amateur pinion, a high speed side pinion and a low speed side pinion fixed to an intermediate shaft to which a first gear that meshes with the amateur pinion, and a high speed side pinion and a low speed side pinion that mesh with the high speed side pinion and the low speed side pinion respectively and are rotatably supported by a clutch sleeve. a high-speed side gear and a low-speed side gear,
It is disposed between the high-speed gear and the low-speed gear, is connected to the spindle with a sprocket, and is movable in the axial direction via the shift lever, so that it can be ratcheted to the end faces of the high-speed gear and the low-speed gear on each side. A gear transmission characterized in that it is provided with the above-mentioned clutch sleeve formed in the above.
