のブレーキ装置。[Claims for Utility Model Registration] (1) A parking brake reinforcing device is connected to a wheel cylinder that is supplied with pressure from a pressure source, and this reinforcing device is connected to a master cylinder device that is operated when the parking brake is applied, and this master cylinder. An auxiliary cylinder device that is driven by the device to generate pressure, and when the auxiliary cylinder device generates pressure, the supply from the pressure source to the wheel cylinder is cut off, and the pressure generated by the auxiliary cylinder device is supplied to the wheel cylinder. A brake device comprising a switching valve configured as follows. (2) A switching valve is integrally incorporated in the auxiliary cylinder device, and closes the pressure source supply path by reciprocating the piston in the auxiliary cylinder device, and also connects the cylinder chamber in the auxiliary cylinder device to the wheel cylinder. 2. The brake device according to claim 1, wherein the brake device is configured to open a road. (3) The brake device according to claim 1, wherein the master cylinder device is configured to be operated only during parking brake.
