Abstract: During normal operation of a braking force generating device, the wheels are braked by braking force generating device when a depressing force cut-off valve is closed by energizing its solenoid to cut off communication between a master cylinder and wheel cylinders. When an abnormality occurs, a master cylinder generates a brake fluid pressure upon a driver's braking operation, and supplies it to the wheel cylinders when the depressing force cut-off valve is opened by de-energizing its solenoid. When the depressing force cut-off valve is closed, such as during normal operation, since the depressing force cut-off valve functions as a one-way valve that is urged in a valve-closing direction due to a brake fluid pressure generated by the master cylinder, an electromagnetic force generated by the solenoid is smaller, thereby reducing the power consumption of the solenoid.
