PROBLEM TO BE SOLVED: To provide a vehicular brake fluid pressure control device in which a suction chamber which allows brake fluid from a reservoir chamber of a reservoir to flow thereinto and communicates with a suction side of a fluid pressure pump is formed in a body and a suction valve, which is closed according to output of fluid pressure from a master cylinder in a non-operated state of the fluid pressure pump and opened according to decrease in fluid pressure of the suction chamber and reduction of volume of the reservoir chamber accompanying operation of the fluid pressure pump, is provided between a master cylinder and the suction chamber, which is configured so as not to suction excessively fluid pressure at a wheel brake side in a state where a reserve piston is moved to a position that makes the volume of the reservoir chamber minimum by operation of the fluid pressure pump.SOLUTION: In a state where a reservoir piston 32 is moved to a position that makes the volume pf a reservoir chamber 26 minimum, a space between a suction chamber 25 and the reservoir chamber 26 is blocked with a seal member 80.SELECTED DRAWING: Figure 4 |
