とする荷重応答型制動液圧制御装置。 It includes a proportioning valve that controls the brake fluid pressure supplied from the master cylinder to the wheel cylinders, and a spring biasing mechanism that engages with the piston in this valve to control the operation of the valve according to the vehicle's carrying load. This spring biasing mechanism is interposed between a lever that comes into contact with the piston and a bracket that moves up and down relative to the lever and the lever depending on the load of the vehicle, so that it can slide against the bracket. a rod that is spherically engaged with the lever and movably engaged with the lever; and a rod that is interposed between the rod and the lever to elastically maintain the spherical engagement and direct the lever toward the piston. In the load-responsive brake hydraulic pressure control device, the first member is provided on the rod side and has a concave surface on the lower side, and the first member is provided on the bracket side and has a concave surface on the lower side. A viscoelastic material that allows the spherical engagement to be obtained by engagement with a second member having a convex surface on the upper side that is joined to the rod, and that allows the first or second member to be elastically deformed in the axial direction of the rod. A load-responsive brake hydraulic pressure control device characterized by being formed by.
