Claims

[Scope of utility model registration request]

a piston, a housing having an inlet port connected to the master cylinder and an outlet port connected to the rear wheel cylinder, slidably supporting the piston such that one end of the piston protrudes into the atmosphere; a valve member supported and capable of abutting and separating from the piston in response to sliding movement of the piston, the inlet port and the outlet port communicating through a fluid passageway formed by the housing and the piston; When the piston and the valve member come into contact, communication of the fluid passage is cut off, and when the piston and the valve member are separated, the fluid passage is connected between the inlet port and the valve member in a brake fluid pressure control valve in which the fluid passage communicates with the piston and the valve member. and a second liquid passage between the outlet port and the valve member, and characterized in that the housing is provided with a communication hole that communicates the vicinity of the valve member of the second liquid passage with the outlet port. Brake fluid pressure control valve.
