[Claims for Utility Model Registration] (1) A suspension spring disposed between a sprung member and an unsprung member, and a valve piston protruding outward from the valve body in a vertical direction, a pressure reducing valve attached to either one of the sprung member and the unsprung member to reduce the brake fluid pressure supplied from the brake master cylinder to the wheel cylinder of the wheel corresponding to the suspension spring; and the suspension spring. is attached to a portion where the amount of relative displacement with respect to the one is smaller than the amount of relative displacement between the sprung member and the unsprung member, and is engaged with the protruding end of the valve piston to reduce the amount of compression of the suspension spring. A load-sensing brake fluid pressure control device comprising: a spring member whose elastic deformation increases as the load increases, and which applies a biasing force to the valve piston of a magnitude corresponding to the load applied to the suspension spring. (2) The suspension spring is a coil spring, and the pressure reducing valve is attached to the sprung member with the valve piston protruding downward from the valve body and in a direction substantially parallel to the center line of the coil spring. 2. The load-sensing brake fluid pressure control device according to claim 1, wherein the spring member is supported by a vertically intermediate portion of the coil spring. (3) The suspension spring is a leaf spring, and the pressure reducing valve is attached to the sprung member with the valve piston protruding downward from the valve body, and the spring member is attached to the spring member such that the valve piston protrudes downward from the valve body. The load-sensing brake fluid pressure control device according to claim 1, which is attached to an intermediate portion between a connecting portion to the sprung member and a connecting portion to the unsprung member.
