する車両ブレーキ装置。A front power piston, which has a diaphragm and is provided in the shell body via the diaphragm, moves the inside of the shell body into four chambers, a front chamber and a rear chamber, of the front power piston and rear power piston, respectively. Definition 1-1 A valve mechanism is provided in the rear power piston to control pressure between a front chamber and a rear chamber of the rear power piston in conjunction with an input member, and when the input member is actuated, the rear power piston is operated. A pneumatic type that transmits the thrust that acts on the power piston to the output shaft when a pressure difference is created between the front chamber and the rear chamber of the piston, and transmits the reaction force that acts on the output shaft to the input member. In a vehicle brake system using a booster, a control valve mechanism for controlling a differential pressure between a front chamber and a rear chamber of the rear power piston is connected to a rear chamber of the rear power piston, and the control valve mechanism controls the rear power A vehicle brake device characterized in that fluid introduced into a rear chamber of the front power piston is controlled based on a pressure difference between a front chamber and a rear chamber of the piston.
