<P>PROBLEM TO BE SOLVED: To preclude a position of a braking operation member from being varied in automatic braking, and to preclude a relation between an operation input and a stroke from being varied even when the braking operation member is operated during execution of the automatic braking, so as to enhance braking operation feeling, in a vehicular brake fluid pressure controller for operating a master cylinder by booster hydraulic pressure provided by governing hydraulic pressure from a hydraulic pressure supplying source. <P>SOLUTION: A pressure governing valve cylinder 31A is engaged slidably with the second cylinder body 30 in a rear side of a master piston 9, an input transmission mechanism 4A having simulator springs 64, 65 is provided between a sliding member 32 engaged slidably with the valve cylinder 31A and a brake operation member 1, the hydraulic pressure supplying source 2 is connected to a booster hydraulic chamber 28 via the first opening and closing valve 75, and a reservoir R is connected to a release port 53 via the second opening and closing valve 76. <P>COPYRIGHT: (C)2004,JPO |
