PURPOSE:To quicken a proper car height return, by making a car height proper by outputting to control valves the operation fluid pressure command values of fluid pressure actuators according to detection car heights, and at the same time, arranging so that command values may be restrained in such a way that the pressures of actuators become within a predetermined extent in accordance with this car height control. CONSTITUTION:A controller 30, so as to make a car height proper by means of detection car heights from car height sensors 33FL-33RR, outputs to control valves 7FL-7RR the command values of the operation fluid pressures of fluid pressure actuators 5FL-5RR, and the car height is adjusted. And, according to a car height control, output command values are controlled so that operation fluid pressures occurring at fluid pressure actuators 5FL-5RR may be contained within a predetermined pressure extent. As a result, the operation fluid pressures of fluid pressure actuators can be rapidly returned to a proper value.
