Claims (1)

[Scope of claim for utility model registration] When vehicle deceleration is detected, the inertia valve moves to seat on the valve seat and confine the hydraulic pressure on the back of the actuator piston, and set the pressure reduction starting point according to the contained hydraulic pressure. In a load-responsive hydraulic pressure control valve that is set to a pressure control mechanism and controls the hydraulic pressure to the rear wheel cylinder to be reduced, 1. Liquid is formed on the chamber wall on the forward side of the inertia valve of the valve chamber in which the inertia valve is removably housed. The inflow passage is opened, and the inflow passage is inclined at an angle of 10° to 30° with respect to the line connecting the center of the inertial valve and the center of the valve seat, and the extension line of the inflow passage passes approximately through the center of the inertial valve. A load-responsive hydraulic control valve characterized by:
