PROBLEM TO BE SOLVED: To provide a hydraulic clutch release device capable of reducing increase in an axial and a radial direction, and increase in hydraulic amount, free from the oil leakage and the galling of a piston, small in inclination and capable of being easily assembled and disassembled. SOLUTION: A hydraulic clutch release device comprises a piston 7 inserted into an annular cylinder chamber 3, a bearing 30 of which an inner ring 32 is contacted with a diaphragm spring 40, and a spring 47 for energizing the bearing to the diaphragm spring side, a cylindrical part 11 contacted with a point of the piston, a bent part 12 radially extended from the cylindrical part and further bent to an annular cylinder side, a front hub 10 formed by a front plate 13 further radially extended, a rear hub 14 formed by a disc-like rear plate 17 slidably contacted with an outer periphery of an outer ring of the annular cylinder, and an outer ring of a bearing are mounted on the front plate end, and the outline parts of the rear plate and the front plate, the outer ring 31 and an elastic member 8 for holding a bearing are crimped by a cover 9.
