PURPOSE: To improve control accuracy of rotary speed of the output side of a wet type multiplate hydraulic clutch. CONSTITUTION: A device is formed in such a constitution that the inner disk and the outer disk of a wet type multiplate hydraulic clutch are tightly fitted by a hydraulic cylinder unit 4 which rotates integratedly with the inner disk, and rotary speed is controlled at the time of operation in a slip condition. A prime mover 1 which rotates at set rotary speed is connected to a first shaft, and the output side of the wet type multiplate hydraulic clutch 3 is connected to a second shaft through a power transmission mechanism. A differential gear device 7 is provided so as to output a rotary speed difference between the output side rotary speed of the wet type multiplate hydraulic clutch 3 and set rotary speed from a third shaft which is connected to the first and second shafts through a differential gear mechanism. And also an operating oil pressure controlling means 8 is provided so as to control pressure of operating oil which is supplied to the hydraulic cylinder unit 4 according to the output result of the differential gear device 7.
