To inhibit pressure rising characteristics of a brake from being changed by influence of cavitation.SOLUTION: A brake fluid pressure control device includes: a reservoir tank 15; a master cylinder 10 which is connected to the reservoir tank 15 to generate a fluid pressure of a working fluid; and a slave cylinder 20 which generates a fluid pressure of the working fluid by an electric actuator. Further, the brake fluid pressure control device includes: control valve means 30 which controls a fluid pressure of the working fluid acting on the wheel cylinder W; and a main tank 80 which is formed separately from the reservoir tank 15. Furthermore, the brake fluid pressure control device includes a return fluid passage 9b into which the working fluid released from the wheel cylinder W through the control valve means 30 flows during pressure reduction control of the fluid pressure of the working fluid acting on the wheel cylinder W. The main tank 80 and the reservoir tank 15 are connected by a first connection passage and the return fluid passage 9b and the main tank 80 are connected by a second connection passage.SELECTED DRAWING: Figure 1

    【課題】キャビテーションの影響によってブレーキの昇圧特性が変化することを抑制する。【解決手段】ブレーキ液圧制御装置は、リザーバタンク15と、リザーバタンク15に接続され作動液の液圧を発生させるマスタシリンダ10と、電動アクチュエータによって作動液の液圧を発生させるスレーブシリンダ20と、を備えている。また、ホイールシリンダに作用する作動液の液圧を制御する制御弁手段30と、リザーバタンク15と別体のメインタンク80を備えている。また、ブレーキ液圧制御装置は、ホイールシリンダWに作用する作動液の液圧の減圧制御時に、制御弁手段30を通じてホイールシリンダWから逃がされる作動液が流入する戻り液路9bを備えている。メインタンク80とリザーバタンク15とは第一接続路で接続され、戻り液路9bとメインタンク80とは第二接続路で接続されている。【選択図】図1
