PURPOSE: A clutch operating device for a vehicle is provided to easily intermit a clutch than operations of an existing clutch pedal and accordingly to reduce fatigue of a driver. CONSTITUTION: A clutch operating device(100) for a vehicle is composed of a pressure on/off valve(110), a pressure on/off valve operating button, a pressure distributing valve(130), a hydraulic cylinder(140), a booster(150), a pressure regulating valve(160), and a pressure on/off valve power cut-off device. The pressure on/off valve is opened and closed by the on and off of a power supply unit to supply and cut off pressure supplied from a pressure source. The pressure on/off valve operating button is installed to a shift lever to open the pressure on/off valve by a pressing operation. The pressure distributing valve has plural distributing holes to distribute pressure supplied from the pressure source in opening the pressure on/off valve. The hydraulic cylinder supplies the generated pressure through a piston(142) to a clutch booster and cuts off a clutch(12). The booster applies power in the direction of turning to the original position by elastic force of a restoring spring, has a booster piston(152) connected with the piston of the hydraulic cylinder, and operates the hydraulic cylinder by boosting pressure supplied from the pressure distributing valve by the on-state of the pressure on/off valve. The pressure regulating valve is connected between the piston of the hydraulic cylinder and the booster piston to move with the moving distance to forward and backward moving directions of the two pistons and regulates pressure to connect the clutch by discharging pressure supplied from the pressure distributing valve. The pressure on/off valve power cutting device turns off power supplied to the pressure on/off valve and closes the pressure on/off valve if the pressure regulating valve moves with a set distance. |
