To provide a vehicular braking device that can prevent liquid pressure from being generated excessively in an electric cylinder and a liquid passage, in ABS control, even when fluid is supplied from a master cylinder to a wheel cylinder before a master cut valve is closed.SOLUTION: The vehicular braking device comprises: a pump 315 that inhales fluid in a low-pressure reservoir 317 and discharges fluid to a space between master cut valves 41 and 42 and a holding valve 313, on liquid passages 61 and 62; a pump activating part 921 that activates the pump 315 when ABS control is executed in a state where a pressurization control part 912 makes an electric cylinder 5 pressurize wheel cylinders 81-84; and a restriction control part 922 that further restricts the volume of fluid discharged by the pump 315 as a position of a piston 53 in a cylinder 51 is located closer to a retreating side, in a state where the pump 315 is activated by the pump activating part 921.SELECTED DRAWING: Figure 4

    【課題】マスタカット弁が閉じる前にマスタシリンダからフルードがホイルシリンダに供給された場合でも、ABS制御において、電動シリンダ及び液路での過大液圧の発生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、低圧リザーバ317のフルードを吸入して、液路61、62においてマスタカット弁41、42と保持弁313との間にフルードを吐出するポンプ315と、加圧制御部912によって電動シリンダ5でホイルシリンダ81~84が加圧された状態でABS制御が実行された場合にポンプ315を作動させるポンプ作動部921と、ポンプ作動部921によってポンプ315が作動されている状態で、シリンダ51内のピストン53の位置が後退側であるほどポンプ315のフルード吐出流量を制限する制限制御部922と、を備える。【選択図】図4
