A liquid volume compensation mask cylinder that replenishes the small diameter chamber that is pressurized by the small diameter piston to generate braking fluid pressure based on the pressure difference between the large diameter chamber and the small diameter chamber, and a power piston that operates based on the pressure difference on both sides. , a control valve piston that is connected to the brake pedal and changes the pressure difference on both sides of the power piston according to the amount of relative movement with the power piston, the output shaft that drives the large diameter piston and the small diameter piston is connected to the reaction disc A booster-equipped liquid volume compensating mask cylinder having a booster for pushing out through a booster, wherein the control valve piston and the power piston move relative to each other as the brake pedal is operated. As a result, the pressure maintained in the large diameter chamber by the relief valve and the difference in pressure receiving area between the large diameter piston and the small diameter piston that receive the pressure are approximately equal to the load force applied to the output shaft. A liquid with a booster, characterized in that a gap is provided between the control valve piston and the reaction disk to transmit the reaction force of the output shaft to the control valve piston when force is generated in the power piston. Volume compensation mask cylinder.
