To suitably perform normal brake control, antilock brake control and pressurization brake control while reducing the number of part items.SOLUTION: A brake fluid pressure control device comprises a fluid pressure circuit U1 arranged between a master cylinder M and a wheel brake R. The fluid pressure circuit U1 comprises a reservoir 4 for storing a working fluid which escapes from the wheel brake R, a normally-closed outlet valve 3 arranged between the wheel brake R and the reservoir 4, and a normally-opened control valve 2 arranged between the master cylinder M and the wheel brake R. The fluid pressure circuit also comprises a pump 5 for sucking the working fluid stored in the reservoir 4, and discharging it between the control valve 2 and the wheel brake R, and a normally-closed suction valve 6 arranged between the master cylinder M and a suction port of the pump 5. The control valve 2, a discharge port of the pump 5 and a fluid path which communicates with the wheel brake R directly communicate with one another.SELECTED DRAWING: Figure 1

    【課題】部品点数を削減しつつ、通常のブレーキ制御、アンチロックブレーキ制御および加圧ブレーキ制御を好適に実行する。【解決手段】マスタシリンダMと車輪ブレーキRとの間に配置される液圧回路U1を備えている。液圧回路U1は、車輪ブレーキRから逃された作動液を貯溜するリザーバ4と、車輪ブレーキRとリザーバ4との間に配置された常閉の出口弁3と、マスタシリンダMと車輪ブレーキRとの間に配置された常開の制御弁2とを備えている。また、リザーバ4に貯溜された作動液を吸引して制御弁2と車輪ブレーキRとの間に吐出するポンプ5と、マスタシリンダMとポンプ5の吸入口との間に配置される常閉のサクション弁6と、を備えている。制御弁2とポンプ5の吐出口と車輪ブレーキRに通じる液路とが直接連通している構成とした。【選択図】図1
