Claims

[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. a valve mechanism disposed parallel to the housing with one end protruding into the housing; an equalizer abutting the protruding ends of the pair of valve cylinders directly or indirectly through another member; a shaft member that penetrates the equalizer substantially perpendicularly to a plane including two axes of the pair of valve pistons and passes through an intermediate position between the two axes, and rotatably supports the equalizer; A support that is provided so as to be immovable relative to the housing at least in use, and that supports one end of the shaft member protruding from the equalizer so as to be rotatable within a plane that is a plane of symmetry of the pair of valve pistons. a member, and a rotational moment is applied to the other end of the shaft member in a direction that biases the equalizer toward the valve piston using the support member as a fulcrum, and whose magnitude increases as the rear wheel load of the vehicle increases. 1. A load-responsive rear independent two-system control hydraulic control valve, characterized in that it includes a spring member that provides pressure.
