PROBLEM TO BE SOLVED: To provide a newly configured vehicle height adjustment device that can widen an available range of the vehicle height adjustment device with a simple structure and improve an added-value of a vehicle.SOLUTION: A vehicle height adjustment device 10 comprises: a plurality of air springs 12 and vehicle height adjustment valves 14 (vehicle height adjustment portions) that are provided corresponding to respective wheels of a vehicle body and adjust a vehicle height according to feeding/draining of working fluid; a pressure tank 26 that serves as a working-fluid supply source; a plurality of open/close valves (a first open/close valve 24a, a second open/close valve 24b, a third open/close valve 24c and a fourth open/close valve 24d) interposed between the air springs 12 sides and the pressure tank 26; and an ECU 56 (a control portion) that adjusts vehicle heights of the air springs 12 in a storage vehicle-height range where vehicle heights are restricted to a lower vehicle height than a central value within a vehicle height adjustable range of the air springs 12 and within a travelling vehicle-height range allowable while travelling the vehicle. The ECU 56, when a predetermined vehicle stopping condition is satisfied, adjusts the vehicle heights of the air springs 12 to any position in the storage vehicle-height range. |
