Claims

[Claims for Utility Model Registration] A main body including an inlet side liquid chamber connected to a master cylinder and an outlet side liquid chamber connected to a brake cylinder, and the inlet side liquid chamber and the outlet of the main body. a piston that is slidably inserted between the side liquid chamber and has a larger pressure-receiving area on the side facing the inlet side than the outlet side; and the inlet side liquid chamber and the outlet side liquid chamber. a communication passage formed in the piston that communicates with the piston; and a valve provided in the outlet side liquid chamber for opening and closing the communication passage and biased toward the opening of the communication passage by a spring member. A hydraulic control valve comprising: a mechanism;
