PURPOSE: A clutch-operating device is provided to reduce the manufacturing cost, improve balance of rotary portion of a clutch, and reduce rotational inertia of the clutch by simplifying the structure of a clutch disk. CONSTITUTION: A clutch-operating device comprises a master cylinder(2); an accumulator cylinder(3) having hydraulic space connected with hydraulic space of the master cylinder; an accumulator piston(4), dividing the space of the accumulator cylinder into hydraulic space and atmospheric space; accumulator springs(5), having elastic forces increased as the accumulator piston is moved in the opposite direction of the hydraulic space; a hydraulic line(7), connecting the hydraulic space of the accumulator cylinder and hydraulic space of a release cylinder(6); a check valve and an orifice, controlling the hydraulic flowing ; an isolation valve(8) and springs, and a spring(90) load relief valve(9), discharging fluids the over reference value to the outside of the hydraulic space when the hydraulic pressure of the hydraulic space of the clutch is over the reference value. Thus, the structure of the clutch is simplified by not installing a cushion plate to a clutch disk.
