Claims

[Scope of utility model registration request]

A hydraulic piston is opposed to the friction member at an axial distance, a spring locking portion is formed on the piston sliding shaft, and the inner peripheral end of the disc spring is brought into contact with the locking portion, and the outer peripheral end of the disc spring is brought into contact with the locking portion. By bringing the part into contact with the piston, the hydraulic piston is urged toward the clutch disengagement side, and when the clutch is disengaged, a constant gap is maintained between the middle part of the disc spring and the friction member, and the hydraulic piston moves a constant stroke toward the clutch engagement side. A hydraulic clutch characterized in that the friction plate is pressed by the intermediate portion of the disc spring when the clutch is pressed.
