Claims (2)

[Scope of utility model registration request] (1) When the set deceleration is reached, the inertia valve operates to confine hydraulic pressure to the actuator piston, and the actuator piston moves according to the contained hydraulic pressure to compress the spring and reduce the hydraulic pressure to the rear wheel cylinder. In a load-responsive hydraulic pressure control valve that sets a pressure reduction control start point of a hydraulic pressure control mechanism, an orifice provided in a liquid supply passage leading to a valve chamber of the inertial valve is thermally expanded by a material forming the liquid supply passage. A load-responsive hydraulic control valve characterized by being made of a material with a large coefficient. (2) The load-responsive hydraulic control valve according to claim 1, which is a registered utility model, wherein a plate is press-fitted into the orifice to limit expansion in the longitudinal direction so as to allow expansion changes of the orifice only in the radial direction.
