ら成るアンチスキツドブレーキ制御装置。[Claims for Utility Model Registration] (1) A hydraulic control valve disposed between a master cylinder and a wheel brake actuating device, a loosening circuit connected to the hydraulic control valve, and the hydraulic control valve. Pressurizes the brake fluid discharged from the wheel brake actuation device to the release circuit via the recirculation circuit, and returns the fluid to the pressure fluid supply pipe connecting the master cylinder and the hydraulic pressure control valve via the recirculation circuit. In the anti-skid brake control device having a pressure pump, the pressure fluid supply pipe is provided closer to the master cylinder than the reflux circuit connection part, and is connected at least from the reflux circuit connection part side to the master cylinder side. An anti-skid brake control device comprising: a valve device capable of cutting off fluid communication; and a throttle connecting an input side and an output side of the valve device. (2) Hydraulic pressure control that controls the brake fluid pressure of the wheel cylinder in response to commands from the control unit that is disposed between the master cylinder and the wheel cylinder of the wheel brake device and evaluates the skid state of the wheel. a reservoir for storing brake fluid discharged from the wheel cylinder via the hydraulic pressure control valve when the brake fluid pressure is lowered by control of the hydraulic pressure control valve; pressurizing the brake fluid in the reservoir; a hydraulic pump that returns the fluid to a pressure fluid supply line connecting the master cylinder and the hydraulic pressure control valve; and a hydraulic pump that is connected to the pressure liquid supply line and directs the direction from the master cylinder to the hydraulic pressure control valve. a first check valve whose forward direction is connected to a conduit connecting the master cylinder and the wheel cylinder, and whose forward direction is from the wheel cylinder to the master cylinder; and a throttle connected between an input port side and an output port side of the first check valve and bypassing the first check valve.
