PURPOSE:To make the car level control performable in a stable manner even in time of driving, by constituting fluid resistance in a pipe line between a level-control actuator and a fluid pressure source so as to be altered with a driving state detecting signal. CONSTITUTION:A car speed signal DV out of a car speed detector 18 and each car level detecting signal out of car level detectors 17a and 17b are all inputted into a controller 20. On the basis of these inputted signals, the controller 20 controls an exhaust valve 12b, charging and exhaust valves 12c and 12d, and a fluid resistance change valve 12e, adjusting a car level. At this time, the fluid resistance in a pipe line 8 is made smaller by the fluid resistance valve 12e in time of driving, but a level-control speed is increased instead. With this constitution, the stable level control in times of driving and stoppage either is performable. |
