PURPOSE:To prevent malfunction of hydraulically driven equipments due to oil pressure loss by transmitting vibrations caused by a vehicle being driven to a hydraulic pressure generator comprising a small plunger pump and by supplying the generated pressure oil into a hydraulic circuit. CONSTITUTION:A hydraulic pressure generator f is connected to a line 14 supplying pressure oil discharged from a pump p to a hydraulically driven device a. The hydraulic pressure generator f comprises a hydraulic cylinder 7 of a small plunger pump receiving vibrations of a vehicle being driven, a suction check valve 9, and a discharge check valve 10, all interposed between the line 14 and a tank 13 so as to supply pressure oil to a hydraulic circuit utilizing the vibrations of the running vehicle. Thus, hydraulic pressure loss is prevented so that the hydraulically driven device a can be operated accurately.
