PURPOSE:To prevent the power loss on idle revolution by supporting a gear by a supporting shaft through a plain bearing on loaded state and through a roller bearing on idle revolution. CONSTITUTION:The front edge part of a supporting shaft 15 is fixed concentrically onto an input shaft, and an output pinion 11 is a slender cylindrical body continuous to a clutch output part 10. Each outer periphery of an elastic body 22 is fitted onto the inner surface 22. The outer periphery of a needle-shaped roller bearing 23 is fitted onto the inner surface of the elastic body 22, and the inner surface of the bearing 23 is fitted onto the outer surface of the supporting shaft 15. When the pinion 11 idly revolves, the elastic body 22 is not deformed, and the pinion 11 is supported onto the supporting shaft 15 through the needle-shaped roller bearing 23 only, and the power loss due to the idle revolution of the pinion 11 is very small. When the pinion 11 transmits a power, the elastic body 22 is deformed, and the pinion 11 is supported by the supporting shaft 15 through a bush 26. |
