PROBLEM TO BE SOLVED: To eliminate necessity in an active type seismic control system for always continuously supplying pressure liquid from a pressure accumulator during vibration of a structure and enable a surplus control power to be outputted efficiently further.;SOLUTION: This invention relates to a driving device 2 for outputting a control force to be applied to a structure by using pressure liquid got from a source of energy 1 storing pressure liquid. The driving device 2 comprises: a cylinder 21 filled with pressure liquid; a piston 22 reciprocated in the cylinder 21; a servo valve 25 connected between each of cylinder chambers 23 and 24 at both sides holding the piston 22 and the source of energy 1 for controlling a flowing of pressure liquid within the source of energy 1 into each of the cylinder chambers 23 and 24; and a flow rate control valve 26 connected between the cylinder chambers 23 and 24 at both sides so as to control the amount of motion of pressure liquid between the cylinder chambers 23 and 24 at both sides.;COPYRIGHT: (C)2015,JPO&INPIT
