PROBLEM TO BE SOLVED: To provide an air suspension device improved in responsiveness and controllability in height adjustment by performing the adjusting work for raising and lowering height in a short time. SOLUTION: An exhaust solenoid valve 23 is provided through an exhaust pipe 24 on the way of a main pipe 21 connected to a discharge opening 18 of a scroll compressor 1. The main pipe 21 is connected to each of air springs 26A-26D of the vehicle through branch pipes 27A-27D and opening/closing valves 28A-28D. An air tank 30 storing the exhaust air discharged from the air springs 26A-26D inside thereof is connected to the main pipe 21 through a tank pipe 29 and a direction control valve 32. When the direction control valve 32 is switched to a switching position 3, the exhaust air inside the air tank 30 is sucked into a compression chamber of the scroll compressor 1 from a re-compression pipe 31 under the pre-compression condition.
