PURPOSE:To avoid the lack of oil quantity in a pressure accumulating means and enable always proper vehicle posture control by providing a pressurizing pressure regulating means which detects the oil pressure of said pressure accumulating means and controls a pressurizing means, and a second pressurizing pressure regulating means which operates said pressurizing means at every defined time. CONSTITUTION:A hydraulic control suspension M5 is fed with oil pressure in a pressure accumulating means M1 which accumulates oil pressure fed from a pressurizing means M2, and control a vehicle posture. The oil pressure of the pressure accumulating means M1 is detected by oil pressure detecting means M3 and, when the detected oil pressure is below a lower limit value the pressurizing means M2 is operated by a first pressurizing pressure regulating means M4 to increase the oil pressure in the pressure accumulating means M1 to an upper limit value. In such an oil pressure feeding device, a second pressurizing pressure regulating means M6 which operates the pressurizing means M2 for every defined time to increase oil pressure in the pressure accumulating means M1 is provided. Thereby, frequency at which the oil pressure in the pressure accumulating means M1 is lowered to the vicinity of the lower limit value can be reduced, enabling always secure vehicle posture control. |
