PROBLEM TO BE SOLVED: To obtain a fluid pressure brake device capable of more quickly transmitting pressurizing force of an accumulator to a wheel cylinder.SOLUTION: A fluid pressure brake device includes: a fluid pressure transmission circuit which transmits fluid pressure to a wheel cylinder; a return fluid pressure circuit which delivers brake fluid of the wheel cylinder to the fluid pressure transmission circuit by a pump; an accumulator which is connected to the fluid pressure transmission circuit via a path which does not pass through the pump and is connected to a suction side of the pump; a valve section which is interposed between the accumulator, the fluid pressure transmission circuit, and the return fluid pressure circuit; and a control section which controls the valve section when determining that pressurization of the brake fluid within the wheel cylinder by the accumulator without interposing the pump is required, communicates the accumulator with the fluid pressure transmission circuit, and shuts off the accumulator and the return fluid pressure circuit.SELECTED DRAWING: Figure 1

    【課題】例えば、アキュムレータの加圧力をホイールシリンダへより急速に伝達することができる液圧制動装置を得る。【解決手段】液圧制動装置は、ホイールシリンダに液圧を伝達する液圧伝達回路と、ポンプによってホイールシリンダのブレーキ液を液圧伝達回路に送る、戻り液圧回路と、ポンプを通らない経路を介して液圧伝達回路に接続されるとともに、ポンプの吸入側に接続されたアキュムレータと、アキュムレータと液圧伝達回路および戻り液圧回路との間に介在した弁部と、ポンプを介さずにアキュムレータによるホイールシリンダ内のブレーキ液の加圧が必要であると判定した場合に、弁部を制御して、アキュムレータと液圧伝達回路との間を連通しかつアキュムレータと戻り液圧回路との間を遮断する制御部と、を備えている。【選択図】図1
