Claims

[Scope of Claim for Utility Model Registration] (1) On the main shaft 1 connected to the engine, from one side in the axial direction to the other side, a high-speed loose-fitting gear 11 and a medium-speed loose-fitting gear 10 are installed in this order so as to be freely rotatable. The low-speed loose-fit gear 9 is disposed on a boss extending toward one side from the medium-speed loose-fit gear 10, and the engagement tooth portion 11b is disposed on the other side of the high-speed loose-fit gear 11. , the engagement tooth portion 9b is placed closer to one side of the low-speed loose-fit gear 9, and the medium-speed loose-fit gear 10 is further placed closer to one side at a certain distance.
The engaging tooth portion 10b is formed on the main shaft 1,
A spline portion 1a having the same diameter as the engaging tooth portions 11b and 10b is formed between the engaging tooth portions 11b and 10b.
A first transmission device A is constructed by installing a sliding body 6 that selectively meshes with the gears 6 and 9b so as to be non-rotatable but slidable, and the high-speed loose gear is mounted on the intermediate shaft 2 at the lower stage of the main shaft 1. 11. Gears 14, 16, 17 that mesh with the low-speed loose-fit gear 9 and the intermediate loose-fit gear 10, respectively, are fixed, and the gear 15, which has an intermediate diameter between the fixed gears 16, 17, is used for sliding movement of the sliding body 6. Installed facing each other in the space,
On the clutch shaft 3 at the lower stage of the intermediate shaft 2, there is a reverse gear 21 that directly meshes with the high-speed loose fit gear 11, a forward third speed gear 19 that meshes with the fixed gear 16, and a forward gear 21 that meshes with the fixed gear 15. 2nd speed gear 18, fixed gear 17
The gears 20 for the first forward speed meshing with the gears 20 are freely rotatably supported in order to be selectively fixed to the shaft 3 by the clutch members A, B, C, and D on the clutch shaft 3, respectively. A transmission device comprising B. (2) In the transmission device according to claim 1 of the utility model registration claim, the boss portion of the medium-speed loose-fit gear 10 that is loosely fitted onto the main shaft 1 and on which the low-speed loose-fit gear 9 is loosely fitted on the outer periphery is The sliding part 1 is divided into two parts and provided on both sides.
A transmission characterized in that a medium-speed loose fit gear 10 is formed integrally with a locking gear 10b by being connected by 0c and 10d.
