    摘要： A driving device of a work machine, such as a hydraulic shovel, includes a power generator (32) adapted to be driven by an engine (31), and a power storage means (33) for storing the electric power generated by the power generator (32). Electric motors (45) and a motor generator (54), each of which is adapted to be operated by electric power supplied from either one of or both the power generator (32) and the power storage means (33), respectively drive pumps (46) and a pump motor (52). Supporting circuits (61),(63),(65) for feeding supporting hydraulic oil are provided between a plurality of driving circuits (41),(42),(43) that serve to drive a plurality of hydraulic actuators of a working unit by means of oil hydraulics generated by the pumps (46) and the pump motor (52). By enabling the plurality of driving circuits to effectively share excess energy, the invention makes possible a compact construction of a driving device of a work machine.
