To enable a passenger to certainly recognize an emergency stop of a vehicle in advance, when a driver is brought into an abnormal state and stops the vehicle in an emergency.SOLUTION: A brake device 1 includes: a first fluid pressure supply system A which is equipped with a first decompression valve 21A decompressing the pressure of a signal fluid to be a first pressure Pr1, and a first channel switch valve 23A switching a channel of the signal fluid from a close state to an open state; and a second fluid pressure supply system B which is equipped with a second decompression valve 21B decompressing the pressure of the signal fluid to be a second pressure Pr2 that is higher than the first pressure Pr1, and a second channel switch valve 23B switching the channel of the signal fluid from a close state to an open state later than the first channel switch valve 23A.SELECTED DRAWING: Figure 1
【課題】ドライバーが異常状態に陥って車両を緊急停止させる際、車両が緊急停止することを前もって同乗者に確実に認識させること。【解決手段】ブレーキ装置1が、信号用流体の圧力を第1の圧力Pr1に減圧する第1の減圧弁21Aと、信号用流体の流路を閉状態から開状態に切り替える第1の流路切替弁23Aと、を備える第1の流体圧供給系統Aと、信号用流体の圧力を第1の圧力Pr1よりも高い第2の圧力Pr2に減圧する第2の減圧弁21Bと、信号用流体の流路を第1の流路切替弁23Aよりも遅れて閉状態から開状態に切り替える第2の流路切替弁23Bと、を備える第2の流体圧供給系統Bと、を備える。【選択図】図1
