きく形成したことを特徴とするブレーキ液圧制御弁。A spring cal control chamber is defined within the main body by a pressure-responsive valve that communicates or shuts off the inlet and outlet of - according to the displacement thereof, and a plunger that always biases the pressure-responsive valve in the valve-opening direction. , a brake fluid pressure control valve in which the spring force control chamber is controlled by an inertia valve that responds to inertia; an inlet of the chamber is connected to the outlet via a first passage, the first passage and the spring force control chamber are connected via a second passage, and the first passage has a the differential piston that communicates and cuts off communication between the first passage and the second passage is always biased in the direction in which the first passage and the second passage communicate with each other, or in this state and when the other The inflow port and the outflow port are inserted in a state where they are always blocked, and the differential piston is formed with a communication path that communicates the inertia valve housing chamber side with the outflow port, and a side in the direction in which it is biased. A brake fluid pressure control valve characterized in that a pressure receiving area of the valve is formed to be larger than a pressure receiving area on a side opposite to the direction in which the pressure is applied.
