PROBLEM TO BE SOLVED: To provide a fluid pressure control unit which can reduce pulsation generated when pumps are driven, and also restrict enlargement of the fluid pressure control unit.SOLUTION: A fluid pressure control unit 50 comprises multiple pumps 60 for raising fluid pressure of a brake fluid, in one hydraulic circuit. Further, the fluid pressure control unit 50 comprises a discharge flow channel 140 disposed on a discharge side of the multiple pumps 60. The discharge flow channel 140 includes: a confluent flow channel 141 having a downstream side end; and multiple splitting flow channels 142 communicating with the discharge side of the pumps 60. The fluid pressure control unit 50 is provided with a damper unit 80 for damping pulsation of a brake fluid discharged from the pumps 60, in a downstream side region in which a most downstream side connection part 143 out of the confluent flow channel 141 is a reference, when a most downstream side connection part is defined as the most downstream side connection part 143 among connection parts of the confluent flow channel 141 and the splitting flow channels 142.SELECTED DRAWING: Figure 1

    【課題】ポンプの駆動時に発生する脈動を低減でき、液圧制御ユニットが大型化することも抑制できる液圧制御ユニットを提供する。【解決手段】液圧制御ユニット50は、ブレーキ液の液圧を上昇させる複数のポンプ60を、1つの液圧回路に設けている。また、液圧制御ユニット50は、複数のポンプ60の吐出側に設けられた吐出流路140を備えている。吐出流路140は、下流側端部を有する合流流路141と、ポンプ60の吐出側と連通する複数の分流流路142と、を備えている。液圧制御ユニット50は、合流流路141と分流流路142との接続部のうち、最も下流側となる接続部を最下流側接続部143と定義したとき、合流流路141のうちの最下流側接続部143を基準とする下流側の領域に、ポンプ60から吐出されたブレーキ液の脈動を減衰させるダンパユニット80を設けている。【選択図】図1
