PURPOSE:To effectively lubricate a one-way clutch with lubricating oil delivered from the end part of a main shaft, by forming a through hole to a spring holding member and a hollowed groove to the side face of an inner member of the one-way clutch. CONSTITUTION:A through hole 8b is provided to a spring set member 8 holding a belleville spring 12, and a recessed groove 25a is provided to the side face of an inner member 25 of a one-way clutch 20, then a recessed groove 6a is provided to the side face of a clutch center 6. Lubricating oil delivered from the shaft end part of a main shaft 40 is guided along a route 2 to the one-way clutch 20, and lubricating oil discharged from the one-way clutch 20 can be guided to the side of a clutch plate 7 and a clutch disc 4. Utilizing a flow of lubricating oil discharged to the side of a clutch outer 3, the one-way clutch 20 is effectively lubricated. |
