PROBLEM TO BE SOLVED: To provide a hydraulic clutch device that can finely and accurately control torque even at a low clutch operating oil pressure by avoiding an influence of a centrifugal oil pressure associated with high speed rotation in a large hydraulic clutch.SOLUTION: A hydraulic clutch device comprises a first shaft, a second shaft disposed coaxially with the first shaft, a friction transmission mechanism that is disposed between the first shaft and the second shaft and transmits rotational power by friction force or the viscous resistance of oil, and a hydraulic pressing mechanism that rotates together with the first shaft or the second shaft and presses the friction transmission mechanism in an axial direction to change the power transmission torque of the friction transmission mechanism. The hydraulic pressing mechanism has a piston reciprocating in the axial direction to press the friction transmission mechanism, a cylinder accommodating the piston, a first pressure space that is formed between the piston and the cylinder and applies a hydraulic pressure to the piston, and a second pressure space that is formed between the piston and the cylinder and applies a hydraulic pressure to the piston.SELECTED DRAWING: Figure 1
