とするクラツチ倍力装置。 When the master cylinder is inactive, the valve body shuts off the air pressure chamber and variable pressure chamber, and the variable pressure chamber is communicated with the atmosphere, and by depressing the master cylinder, the valve lifter resists the biasing force of the spring. a relay valve and a release valve for communicating the pneumatic chamber and the variable pressure chamber by activating the valve body by the valve lifter and isolating the variable pressure chamber from the atmosphere; The biasing force of the valve toward the valve lifter is set to be larger than the biasing force of the relay valve toward the valve lifter, and the pressure transformation chamber of the relay valve and the transformation chamber of the release valve are selectively connected via a switching valve. While communicating with the power cylinder, the switching valve is linked with the master cylinder,
The switching valve is made to respond to the pressure increasing operation of the master cylinder to communicate the variable pressure chamber of the relay valve to the power cylinder, and is made to respond to the pressure reducing operation of the master cylinder to communicate the variable pressure chamber of the release valve to the power cylinder.
