Claims

[Scope of utility model registration request]

A brake fluid pressure adjustment piston that is installed in the brake fluid pressure circuit from the master cylinder to the wheel cylinder and reciprocates depending on the brake fluid pressure and power fluid pressure to increase or decrease the volume of the brake fluid pressure circuit; A cut valve is provided in the brake fluid pressure circuit leading to the master cylinder and is closed when the brake fluid pressure adjustment piston reciprocates, and a power fluid pressure driven by the engine and supplied to the brake fluid pressure adjustment piston is provided. a hydraulic pump that generates the power hydraulic pressure and supplies the power hydraulic pressure to the power steering gear; and controls supply of the power hydraulic pressure generated by the hydraulic pump to the power steering gear according to the hydraulic pressure of a master cylinder. a regulator valve that adjusts the pressure to a value corresponding to the hydraulic pressure of the master cylinder; and a power fluid that supplies and discharges the power hydraulic pressure regulated by the regulator valve to the brake hydraulic pressure adjusting piston according to the skid state of the vehicle. In response to the fact that the power hydraulic pressure regulated by the pressure supply/discharge valve and the regulator valve is lower than the set value for the hydraulic pressure of the master cylinder, the master cylinder and the wheel cylinder are connected without going through the cut valve. In a vehicle anti-skid device equipped with a communicating bypass valve, the relief valve opens when the power hydraulic pressure regulated by the regulator valve reaches a predetermined value or more, and releases the power hydraulic pressure directly to the power steering gear. An anti-skid device for a vehicle, characterized in that a valve is provided in parallel with the regulator valve.
