Claims

[Scope of Claim for Utility Model Registration] 1. The input shaft 1 that transmits input from outside the transmission case to the inside of the transmission case is connected to the transmission case 2.
It is rotatably supported by a cylindrical support part 4 formed on the end wall 3 of the transmission case 2, and is provided so as to straddle the inside and outside of the mission case 2. An input pulley 5 is attached to the input shaft 1 outside the mission case 2, and the transmission In the transmission structure in which the input bevel gear 6 is fixedly installed in the case 2, the cylindrical support part 4 has an inner diameter bush 7 fitted onto the input shaft 1, an outer diameter bush 8 fitted onto the inner diameter bush 7, and an outer diameter bush 8 fitted onto the inner diameter bush 7. The input pulley 5 and the inner bush 7 are tightened and fixed between the nut 9 and the input bevel gear 6 by means of a nut 9 screwed onto the outer end of the input shaft 1, while the outer bush 8 The grease is engaged with the cylindrical support part 4 so as not to be rotated or slid inwardly of the transmission case, and has an open end on the inner peripheral surface of the outer diameter bushing 8 on the outer surface side of the transmission case 2. This transmission input shaft is characterized in that a reservoir groove 8a is formed and a collar 7a that covers the open end of the grease reservoir groove 8a on the outer end surface side of the outer diameter bushing 8 is integrally formed on the outer end of the inner diameter bushing 8. Support device. 2. A dish-shaped cover member 10 having a peripheral wall portion facing the outer peripheral position of the cylindrical support portion 4 is inserted between the input pulley 5 and the inner bush 7 onto the input shaft 1, and 2. The transmission input shaft support device according to claim 1, wherein the transmission input shaft is fastened and fixed between the input bevel gear and the input bevel gear.
