Claims

[Scope of utility model registration request]

A planetary gear mechanism in which a brake device is provided at the intermediate portion of each final reduction pinion shaft led out from the differential device in the mission case on both sides, and the pinion at the end of the pinion shaft is configured to function as a sun gear. A tractor is provided with a speed reduction device according to the invention, and further has an axle arranged so as to be connected to the carrier of the planetary gear mechanism, wherein the brake case that covers the brake device and the speed reduction case that covers the speed reduction device and the axle have a split structure, A ring gear of a writing planetary gear mechanism is arranged at the end of the deceleration case that comes into contact with the brake case so that its end surface protrudes toward the brake device, and the pressing force when the brake device is activated is applied to the end surface of the ring gear. The structure of a tractor rear axle configured to receive.
