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 |
