PURPOSE:To easily start a car without backing by connecting a clutch master cylinder and a release cylinder to each other with a pipe, with check valve interposed therebetween. CONSTITUTION:When a clutch pedal is stepped on, an oil pressure which is generated in a clutch master cylinder 3 thereat is transmitted into a hole 7 in a hydraulic check valve 4 to shift a piston disposed in the middle thereof, whereby a piston cup 19 is forced to cut off the communication between a hole 15 and another 16. When a brake pedal is stepped on, an oil pressure which is generated in a cylinder 1 is transmitted through a hole 10 in a check valve 5, pushes up a steel ball disposed in the middle thereof and passes through a hole 12 to actuate a wheel cylinder 2. When the clutch pedal is stepped off, the piston 8 is forced back by the repulsion force of a spring 13 so that the oil pressure in the cylinder 2 is transmitted from a hole 12 to a hole 14 in the valve 5, comes into the hole 15 in the check valve 4 passes through the hole 16, is released from the hole 17 to the hole 10 in the valve 5 and then returned into the cylinder 1, thereby starting the car without backing. |
