第１項記載の車両のブレーキ装置。[Claims for Utility Model Registration] 1. A first brake actuator that supplies working pressure from a working pressure supply source to a front wheel brake actuator and a rear wheel brake actuator, respectively, in accordance with signal pressure from a brake valve.
and a second relay valve, and a pressure switching means for relatively changing the supply pressure of at least one of the first and second relay valves during forward movement and reverse movement. . 5 2 The pressure switching means includes a pressure reducing valve that changes the operating pressure amplification factor of the relay valve, a solenoid valve installed in parallel with this pressure reducing valve, and a pressure reducing valve that operates in conjunction with the switching of the solenoid valve during forward movement and backward movement. Utility model registration claim 1, characterized in that the valve is configured as a differential pressure-responsive directional control valve that selectively supplies the signal pressure through the relay valve and the signal pressure through the solenoid valve to the relay valve. Brake device for the vehicle described in Section 1.
