PROBLEM TO BE SOLVED: To provide a vehicular braking device capable of suppressing an increase of load pressure to the components of a braking force applying portion, even if an abnormal condition occurs in a part of the braking force applying portion.SOLUTION: A vehicular braking device includes: a pressure accumulating portion 15c1; a pressure accumulation control portion 17a which controls hydraulic pressure in the pressure accumulating portion 15c1 so as to stop a rise of the hydraulic pressure in the pressure accumulating portion 15c1 when the hydraulic pressure in the pressure accumulating portion 15c1 is predetermined off-pressure or more; a hydraulic pressure generating portion 15d which mechanically generates hydraulic pressure according to brake operation with the hydraulic pressure accumulated in the pressure accumulating portion 15c1 as an upper limit on the basis of the hydraulic pressure in the pressure accumulating portion 15c1; a braking force applying portion 16 which applies braking force on wheels of a vehicle on the basis of the hydraulic pressure generated by the hydraulic pressure generating portion 15d; and an obtaining portion 16a which obtains required braking force. The pressure accumulation control portion 17a lowers the off-pressure when the required braking force obtained by the obtaining portion 16a is a first predetermined value or more.SELECTED DRAWING: Figure 1

    【課題】制動力付与部の一部に異常が発生した場合でも、制動力付与部の他の構成要素への負荷圧の増大を抑制することができる車両の制動装置を提供する。【解決手段】本発明は、蓄圧部15c1と、蓄圧部15c1内の液圧が所定のオフ圧以上である場合に蓄圧部15c1内の液圧の上昇が停止するように蓄圧部15c1内の液圧を制御する蓄圧制御部17aと、蓄圧部15c1内の液圧に基づいて蓄圧部15c1に蓄圧されている液圧を上限としてブレーキ操作に応じた液圧を機械的に発生させる液圧発生部15dと、液圧発生部15dにより発生されている液圧に基づいて車両の車輪に制動力を付与する制動力付与部16と、要求制動力を取得する取得部16aと、を備え、蓄圧制御部17aは、取得部16aにより取得されている要求制動力が第一所定値以上である場合に、オフ圧を低くする。【選択図】図1
