To provide a vehicle brake fluid pressure control device capable of improving a brake feeling when a brake operator is operated with pressurization control of brake fluid in execution.SOLUTION: A vehicle brake fluid pressure control device comprises a fluid pressure circuit which is arranged between a master cylinder M which generates a fluid pressure of work fluid in accordance with an operation amount of a brake operator and a wheel brake W which is operated with the supplied fluid pressure of the work fluid. The wheel brake W has first wheel cylinders W1 and W1 and a second wheel cylinder W2. The fluid pressure circuit has: a main fluid pressure circuit HP1 from the master cylinder M to the first wheel cylinders W1 and W1; a normally opened solenoid valve and a normally closed solenoid valve which are installed in the main fluid pressure circuit HP1; and a pressurized fluid pressure circuit HP2 which is branched from a position between the normally closed solenoid valve and the first wheel cylinders W1 and W1 in the main fluid pressure circuit HP1 and leads to the second wheel cylinder W2.SELECTED DRAWING: Figure 1

    【課題】ブレーキ液圧の加圧制御時にブレーキ操作子の操作が行われた際のブレーキフィーリングを向上させることができる車両用ブレーキ液圧制御装置を提供する。【解決手段】ブレーキ操作子の操作量に応じて作動液の液圧を発生させるマスタシリンダMと、供給された作動液の液圧によって作動する車輪ブレーキWと、の間に配置される液圧回路を備えている。車輪ブレーキWは、第1ホイールシリンダW1,W1と第2ホイールシリンダW2とを有しており、液圧回路は、マスタシリンダMから第1ホイールシリンダW1,W1に至る主液圧回路HP1と、主液圧回路HP1に設けられた常開型電磁弁及び常閉型電磁弁と、主液圧回路HP1における常開型電磁弁と第1ホイールシリンダW1,W1との間から分岐し、第2ホイールシリンダW2に至る加圧液圧回路HP2と、を備えた構成とした。【選択図】図1
