たは第2項に記載の車速変速装置。[Scope of Claim for Utility Model Registration] 1. On the gear transmission shaft 16, a large diameter gear 31 for 1st speed is installed with a loose fit, which is engaged with the small diameter gear 29 for 1 gear on the transmission shaft 18 on the preceding stage side and rotated at a reduced speed. Additionally, a vehicle speed change device is provided with a clutch disposed on the gear change shaft 16 for selectively coupling the first-speed large diameter gear 31 to the gear change shaft 16, the clutch comprising: A small-diameter gear 32 integrated with the first-speed large-diameter gear 31 and a gear shift shaft 16
The clutch j4 is configured to be selectively engaged by meshing with internal teeth 34a formed on a large-diameter shift gear 33 that is slidably installed on the gear shift shaft 1.
In addition to -6, a gear reduction mechanism 36.37 is provided with a small diameter output gear 37 which receives input from the small diameter gear 32 and is selectively engaged with the shift gear 33.
37, and the vehicle creep running is obtained by selectively meshing the shift gear 33 with the small-diameter output gear 37 described above. 2. The vehicle speed change device according to claim 1, wherein the shift gear 33 is configured to be able to selectively mesh with the dual gear 30 on the transmission shaft 18. 3. Another transmission shaft 17 for decelerating and rotating the transmission shaft 18 is provided concentrically with the gear transmission shaft 16, and the other transmission shaft 1
7 and the shift gear 33, a clutch 35 is disposed between the shift gear 33 and the clutch 35, which is selectively engaged when the shift gear 33 is shifted. Vehicle speed change device.
