PROBLEM TO BE SOLVED: To provide an air suspension device that allows air in a negative booster of a brake device to be suctioned into a compressor device.SOLUTION: The air suspension device of a vehicle comprises: a brake device which is mounted on a vehicle and has a negative booster (VB); air spring devices (A1-A4) which are mounted on wheels respectively and have air chambers; a compressor device (CP1) that has a discharge port and a suction port and compresses air and discharges the air through the discharge port; control valves (61-64) which are installed between supply/exhaust passages (P1 and P2) through which the discharge port is communicated with and connected to the air chamber; and an electronic control unit (ECU) that controls opening and closing of the control valves and drives and controls the compressor device. Further, the air suspension device comprises a switch valve (91) which is installed between connection passages (P6 and P7) through which the negative booster is communicated with and connected to the compressor device and is switched and controlled by the electronic control unit.SELECTED DRAWING: Figure 1 【課題】ブレーキ装置の負圧ブースタ内の空気をコンプレッサ装置に吸入し得るエアサスペンション装置を提供する。【解決手段】車両に装着され負圧ブースタ（ＶＢ）を有するブレーキ装置と、各車輪に装着され空気室を有する空気ばね装置（Ａ１−Ａ４）と、吐出ポート及び吸入ポートを有し、空気を圧縮して吐出ポートから吐出するコンプレッサ装置（ＣＰ１）と、その吐出ポートを空気室に連通接続する給排流路（Ｐ１，Ｐ２）に介装される制御弁（６１−６４）と、制御弁を開閉制御すると共にコンプレッサ装置を駆動制御する電子制御装置（ＥＣＵ）を備える。更に、負圧ブースタとコンプレッサ装置を連通接続する連結流路（Ｐ６，Ｐ７）に介装され、電子制御装置によって切換制御される切換弁（９１）を備える。【選択図】図１
