PROBLEM TO BE SOLVED: To simplify an oil hydraulic circuit, narrow the space occupied by the circuit in vehicle, reduce the weight of load paplied to the vehicle, and reduce the fuel consumption of the vehicle. SOLUTION: An oil pump 1A for power steering, which is mounted onto a vehicle, is prepared. Based on a parking brake signal, a change-over valve 31 is switched to supply oil from the oil pump 1A to a car height adjusting system (S) in order to adjust the car height. After this car height adjustment, a lift actuating switch 34 is operated so that the oil feeding (by the pump 1A) is switched to a lift 17. |
