とするブレーキ液圧制御弁。 a stepped piston that moves by receiving hydraulic pressure in an inlet chamber connected to the master cylinder and hydraulic pressure in an outlet chamber connected to the rear wheel cylinder from opposite directions; The poppet valve has a poppet valve that opens and closes a passage communicating between the inlet chamber and the outlet chamber by movement of a piston, and a spring that presses the stepped piston in a direction in which the poppet valve opens, and the stepped piston has the poppet valve built therein. A large diameter portion, a medium diameter portion that serves as a sliding portion with a first sealing means disposed on the housing side so as to separate the inlet chamber and the outlet chamber, and a second sealing member that separates the inlet chamber from the atmosphere side. In a brake fluid pressure control valve configured with a small diameter portion that is a sliding portion with a sealing means, an elastic member is interposed between the first sealing means and the second sealing means, and each sealing means is adjusted to a predetermined position. A brake fluid pressure control valve characterized in that the brake fluid pressure control valve is held in a certain position.
