Claims (1)

[Claims for Utility Model Registration] A pair of valve pistons that control the brake fluid pressure of two hydraulic circuits that independently supply brake fluid pressure to the left and right rear brakes of a vehicle are installed in a single housing, mutually. The protruding ends of the pair of valve pistons are connected to each other by a spring through a load transmitting member which is disposed parallel to the housing and has one end protruding out of the housing, and which commonly abuts the protruding ends of the pair of valve pistons. In a hydraulic control valve configured to be applied with a biasing force in a direction to be pushed into a housing, the load transmitting member has a leg parallel to the valve piston, and a leg formed at one end of the leg so as to protrude from the valve piston. a flange portion that abuts the end portion, the flange portion is slidable on a cylindrical member fixed to the housing in the moving direction of the pair of valve pistons, and includes at least the axes of the pair of valve pistons; The legs are fitted together so as to be rotatable in a direction parallel to a plane, and the rotation range of the legs accompanying the rotation is limited to the extent necessary for the valve piston to start hydraulic pressure control only by the rotation. A hydraulic control valve for a rear independent dual brake system, characterized in that a stopper that limits the range of movement is fixed to the housing or a member fixed thereto.
