PURPOSE:To improve fretting resistance of a shaft, by integrally providing an input gear to a subinput gear and eliminating the necessity for lubricating this portion simultaneously arranging both counter shafts relatively rotatable. CONSTITUTION:A subspeed changer 20 is equipped with a subinput shaft 21 and subcounter shaft 22. The subinput shaft 21 is integrally provided with an input gear 21a, and relatively rotatably connected to a left end part 11a of a main input shaft 11. The subcounter shaft 22 is relatively rotatably connected to a cavity part 12a of a main counter shaft 12. In this constitution, when power is directly transmitred from the subinput shaft 21 to the main input shaft 11, the both counter shafts 12, 22 are relatively rotated, and fretting resistance in a connection part of the both counter shafts can be improved. |
