PROBLEM TO BE SOLVED: To provide a hydraulic clutch device capable of varying a clutch operation load with a compact configuration.SOLUTION: A hydraulic clutch device comprises: a clutch engaged/disengaged in response to an axial movement of a push rod 28; and a slave cylinder 32 including a cylindrical piston member 38 connected to a hydraulic supply source and driving the clutch to be engaged/disengaged, the hydraulic clutch device being configured so that a ratchet mechanism 60 is provided between a first piston 41 and a second piston 42 for restricting relative movements of the first piston 41 and the second piston 42 to each other, the ratchet mechanism 60 is actuated when the first piston 41 slidably moves by a predetermined length L in a clutch disengagement direction C1, and the first piston 41 and the second piston 42 integrally slidably move when the first piston 41 subsequently slides in a clutch engagement direction C2. |
