Brake fluid pressure controller for vehicle

摘要

A brake fluid pressure controller (U) for a vehicle having a brake system (K), a brake operation element (L) and a master cylinder (C), the brake system (K) including: a pump (47) configured for being activated and increasing brake fluid pressure to provide braking force to a wheel brake (B) of the other brake system (K) in which the brake operation element (L) is not operated; a cutoff valve (X) which blocks an output fluid pressure passage (A1,A2,RA) leading from a master cylinder-side to a wheel brake-side when the pump (47) is operated; a brake fluid pool (45,46) disposed downstream of the cutoff valve (X) and upstream of the pump (47); and a pressure member (48) configured for being slidably moved by a brake fluid pressure generated on the master cylinder-side relative to the cutoff valve (X) by an operation of the brake operation element (L) and for providing pressure to a fluid pressure passage (A2,RA) leading to the wheel brake (B).
