徴とする荷重応動型液圧制御弁。 A hydraulic pressure control valve that is installed on either the sprung or unsprung side of a vehicle and has an opening/closing piston that protrudes from a hydraulic pressure chamber in a housing, and controls the hydraulic pressure input from the master cylinder to decrease and outputs it to the wheel cylinder. and one end is attached to the housing via a first mounting structure, and the other end is attached to the other of the sprung mass and unsprung mass of the vehicle through the second mounting structure, and the sprung mass of the vehicle is attached to the sprung mass of the vehicle. A load-responsive hydraulic control valve, comprising: displacement detection means for detecting a relative displacement with the unsprung portion and applying a pressing force F corresponding to the relative displacement to the opening/closing piston of the hydraulic pressure control valve; At least one of the structure and the second mounting structure includes a support part having end surfaces facing each other, a rod-shaped shaft member spanning between the support parts and fixed to the support part, and an inner circumferential surface of the shaft member. two first tube bodies and a second tube body that are fitted together and arranged in the axial direction between opposing end surfaces of the support part, at least one of the first tube body and the second tube body being connected to the shaft part; The shaft has an integral flange, one end or the other end of the displacement detection means is rotatably supported on the outside of the shaft, and both axial ends of each of the first tube and the second tube At least one of the surfaces is provided with a deformable protrusion, and when the protrusion deforms, the total length between the outer end surfaces of the two tubes where the first tube and the second tube are in contact with each end surface of the support section is determined. A load-responsive hydraulic control valve, characterized in that the distance is greater than the distance between the two end faces of the support portion.
