する。In addition, the cover plate attached to the through hole is removable, and when the cover plate is removed during maintenance, the other end of the pipe is exposed, so it is easy to check whether the oil passage needs maintenance by supplying hydraulic pressure. In addition, when the pipe is supported so that it can be tilted freely relative to the case, even if the axis of rotation and the through hole do not align, it can be supported floatingly for a long period of time without causing uneven wear on the support part in the center hole of the pipe. In addition, when the pipe is supported via a stopper fixed to it, it is possible to prevent oil leakage in the axial direction of the pipe when pressure oil is supplied from a hydraulic source or when pressure oil is discharged from a clutch. to prevent the movement of
The seal can be made simple, and even if there are multiple clutches on the rotating shaft, by making the pipe an inner fitting pipe, it can be easily supplied separately, and it can be inserted from the outer pipe through the through hole. This serves as a guide for the inner pipe and has the effect of improving its assemblability.
