PURPOSE:To eliminate any slippage between a transmitting body and a every disk by rotatably supporting the cylindrical portion of the transmitting body through a bushing on a piston and interposing a thrust bearing between the end face of the piston and the end face of the flange. CONSTITUTION:The cylindrical portion 31 of a transmitting body 30 is rotatably supported through a bushing 33 on a piston 27, and a thrust bearing 34 is interposed between the end face of the piston 27 and the end face of a flange 32. Thus, the transmitting body 30 does not fall down and the slidable contact between the cylindrical portion 31 and the bushing 33 becomes smooth so that the smooth rotation of the transmitting body 30 can be ensured while slippage between the transmitting body 30 and respective disks 11, 19 can be eliminated since oil does not leak into a cylinder hole 23. |
