To provide a new vehicular brake device which can independently control liquid pressures of wheel cylinders and enables the wheel cylinders to generate liquid pressures even if a failure occurs in one power supply unit.SOLUTION: The vehicular brake device includes: a first liquid pressure generating part 21 which is connected to a first wheel cylinder 81 through a first liquid passage 71 and causes the first wheel cylinder 81 to generate a liquid pressure; a second liquid pressure generating part 22 which is connected to a second wheel cylinder 82 through a second liquid passage 72 and causes the second wheel cylinder 82 to generate a liquid pressure; a first power supply unit 31 which supplies electric power to the first liquid pressure generating part 21; a second power supply unit 32 which supplies electric power to the second liquid pressure generating part 22; and a normally open type communication passage opening/closing part 4 which is provided at a communication passage 73 connecting the first liquid passage 71 with the second liquid passage 72 and opens or closes the communication passage 73.SELECTED DRAWING: Figure 1

    【課題】複数のホイールシリンダの液圧を独立して制御可能であり、且つ、1つの電源部が故障した場合でも、当該複数のホイールシリンダに液圧を発生させることができる新たな車両用制動装置を提供する。【解決手段】本発明は、第1ホイールシリンダ81に第1液路71を介して接続され第1ホイールシリンダ81に液圧を発生させる第1液圧発生部21と、第2ホイールシリンダ82に第2液路72を介して接続され第2ホイールシリンダ82に液圧を発生させる第2液圧発生部22と、第1液圧発生部21に電力を供給する第1電源部31と、第2液圧発生部22に電力を供給する第2電源部32と、第1液路71と第2液路72との間を接続する連通路73に設けられ、連通路73を開閉する常開型の連通路開閉部4と、を備える。【選択図】図1
