を特徴とするブレーキ装置。A switching valve is connected to the rear pressure chamber of the power piston of the brake booster or in the middle of the piping between the master cylinder and the wheel brake, and automatic generation of braking force by the brake booster is achieved by switching the switching valve. Alternatively, in a brake device that maintains braking force, the first detection means detects that the vehicle is stopped, and the second detection means detects that the shift lever is set in a neutral or parking state. a third detection means for detecting depression of the accelerator pedal;
control means for controlling the driving of the switching valve based on the detection results of the second and third detection means, and the control means receives detection signals from both the first, second and third detection means. If the switching valve receives the braking force, the switching valve is maintained in a state in which the braking force is automatically generated or the braking force is maintained.
