PROBLEM TO BE SOLVED: To provide a vehicular brake device capable of suppressing pulsation of a fluid caused by a pump with a simple structure.SOLUTION: A vehicular brake device comprises: a first valve part 51 which is arranged in a hydraulic path A; second valve parts 52, 53 which are arranged between the first valve part 51 and wheel cylinders 14, 15; a pump 57 for discharging a fluid to a space between the first valve part 51 and the second valve parts 52, 53; and a control part 61 for executing pulsation suppression control in which when hydraulic pressure in the wheel cylinders 14, 15 is increased, while actuating the pump 57, the hydraulic pressure on the side of the second valve parts 52, 53 of the first valve part 51 is made larger than the hydraulic pressure on the side of a master chamber 130b of the first valve part 51 by first pressure, by controlling the first valve part 51, and hydraulic pressure on the side of the wheel cylinders 14, 15 of the second valve parts 52, 53 is made smaller than the hydraulic pressure on the side of the first valve part 51 of the second valve parts 52, 53 by second pressure, by controlling the second valve parts 52, 53.SELECTED DRAWING: Figure 4

    【課題】簡素な構成により、ポンプによるフルードの脈動を抑制することができる車両用制動装置を提供する。【解決手段】本発明は、液圧路Aに配置されている第1弁部51と、第1弁部51とホイールシリンダ14、15との間に配置されている第2弁部52、53と、第1弁部51と第2弁部52、53との間にフルードを吐出するポンプ57と、ホイールシリンダ14、15内の液圧を増大させるに際し、ポンプ57を作動させつつ、第1弁部51の制御により第1弁部51の第2弁部52、53側の液圧を第1弁部51のマスタ室130b側の液圧よりも第1圧だけ大きくするとともに、第2弁部52、53の制御により第2弁部52、53のホイールシリンダ14、15側の液圧を第2弁部52、53の第1弁部51側の液圧に対して第2圧だけ小さくする、脈動抑制制御を実行する制御部61と、を備える。【選択図】図4
