PROBLEM TO BE SOLVED: To provide a vehicular braking device capable of at the time of sudden braking, earlier exhibiting braking force relative to a braking operation compared to at the time of normal braking and of eliminating a feeling that it is difficult to depress a pedal.SOLUTION: A first hydraulic pressure generating mechanism 15, a first reaction force generating section D1 and a second reaction force generating section D2 are configured so that volumes of a pressure regulating chamber 15d5, a first reaction force chamber 12d3 and a second reaction force chamber 12d6 are reduced along with an increase in operation amount of a brake operation member 11 in order of the first reaction force chamber 12d3, the pressure regulating chamber 15d5 and the second reaction force chamber 12d6 when operating speed of the brake operation member 11 is less than a predetermined value. A flow between the first reaction force chamber 12d3 and the second reaction force chamber 12d6 is shut off or suppressed when the operating speed of the brake operation member 11 is the predetermined value or more. A first flow passage 91 includes a restriction mechanism 91a for shutting off or suppressing a flow of working fluid when the operating speed of the brake operation member 11 is the predetermined value or more. A second flow passage 41 does not include the restriction mechanism 91a.SELECTED DRAWING: Figure 1

    【課題】急ブレーキ時に、ブレーキ操作に対して通常ブレーキ時よりも早期に制動力を発揮させることができ且つ板踏み感を解消することができる車両用制動装置を提供する。【解決手段】第一液圧発生機構15、第1反力発生部D1、及び第2反力発生部D2は、ブレーキ操作部材11の操作速度が所定値未満である場合に、ブレーキ操作部材11の操作量の増大に伴い、調圧室15d5、第1反力室12d3、及び第2反力室12d6の容積が、第1反力室12d3、調圧室15d5、第2反力室12d6の順で減少するように構成され、第1反力室12d3と第2反力室12d6との間の流通は、ブレーキ操作部材11の操作速度が所定値以上である場合には遮断又は抑制され、第1流路91には、ブレーキ操作部材11の操作速度が所定値以上である場合に作動液の流通を遮断又は抑制する絞り機構91aが設けられ、第2流路41には、絞り機構91aが設けられていない。【選択図】 図1
