とを特徴とする荷重応答型液圧制御装置。 It is used in a rear independent two-system control system that transmits brake fluid pressure to each wheel cylinder installed on the left and right rear wheels of a vehicle through two independent piping systems, and controls the brake fluid pressure transmitted to each wheel cylinder. A pair of pistons that are controlled in cooperation with a pair of valves are assembled in parallel in one housing, one end of each piston protrudes from the housing in a fluid-tight manner so as to be able to slide in the axial direction, and the housing is pivoted. a lever that is movably supported; a spring that applies a biasing force to the swinging end of the lever according to the vehicle carrying load; and a spring that is slidably supported by the housing at both ends and abuts the lever at an intermediate portion The piston is moved according to the vehicle load by a biasing mechanism composed of a support pin in contact with the piston and an equalizer that is swingably supported by the support pin at the center and abuts one end of each of the pistons at both ends. In the load-responsive hydraulic pressure control device, the equalizer has a recessed portion in the center thereof that has an inner surface that makes line contact with the outer periphery of the support pin and restricts movement of the equalizer in the radial direction of the support pin. A load-responsive hydraulic control device characterized by:
