としたブレーキ装置。[Scope of Claim for Utility Model Registration] 1. Applying the pressing force of the brake pedal along with the urging force generated by the brake booster to the master cylinder for braking of a vehicle to generate hydraulic pressure for braking in the master cylinder. In the brake device, a piston that slides in a hydraulic cylinder in conjunction with the swinging of the brake pedal is attached to the brake pedal, and the left and right hydraulic spaces of the hydraulic cylinder are communicated via an opening/closing means, and the piston is connected to the opening/closing means. A brake device characterized in that a control means is connected to the means for closing the means when the above-mentioned pedal force holding information is input. 2 The brake booster has a first chamber and a second chamber separated by a power piston in the brake booster, and the first chamber has a first chamber which is switched from a sealed state to a fluid pressure source and an atmosphere opening port for communication. The first flow path switching means communicates with the second chamber, and the second chamber communicates with the fluid pressure source and the atmosphere opening port from a closed state, respectively, and the control means communicates wheel speed information of the vehicle. A brake device characterized in that said first and second flow path switching means are switched to increase or decrease said master cylinder oil pressure based on skid information obtained in accordance with said skid information.
