とするアンチスキツドブレーキ装置。[Scope of claim for utility model registration] The main brake circuit supplies brake fluid from the master cylinder to the wheel cylinders via a solenoid valve during normal braking, and discharges the brake fluid in the wheel cylinders to the reservoir tank depending on the skidding condition of the wheels. a pressure reducing circuit that reduces the pressure inside the wheel cylinder, and a pump that uses a pump to accumulate the brake fluid in the reservoir tank in an accumulator, and returns the brake fluid from the accumulator to the wheel cylinder via a solenoid valve depending on the skid condition of the wheel. In the anti-skid brake device, a part of the pipe connecting the master cylinder of the main brake circuit and the solenoid valve is formed to pass through the accumulator. At the same time, when the pressure inside the accumulator reaches a predetermined pressure, the brake fluid is only allowed to flow from the accumulator to the conduit, but if there is an abnormality in the accumulator of the accumulator, An anti-skid brake device comprising a check valve equipped with a relief valve mechanism that releases abnormally high pressure to a master cylinder when high pressure is applied.
