PURPOSE: A clutch pedal for a vehicle is provided to reduce expenses and the number of parts without additional space for a master cylinder by generating hydraulic pressure with screwing an arm shaft in a shaft cylinder and moving left in stepping on a pedal, and to improve the clutch pedal effort by reducing loss from mechanical friction. CONSTITUTION: A clutch pedal comprises a pedal arm(10) turning; a clutch shaft connected to the pedal arm; a master cylinder connected to the clutch shaft by a push rod; right and left brackets(20,30); a screw type arm shaft connected to the pedal arm; a stopper(12) installed in the arm shaft; a check valve(13); a bushing connecting unit(18) connecting the pedal arm to the right bracket by a bushing(15) and a fixing bolt(21); and a shaft cylinder(40) embedding the screw type arm shaft through oil seals and directly converting rotation into piston motion. Hydraulic pressure is formed with screwing the arm shaft in the shaft cylinder and moving to the left in stepping on the pedal.
