To improve vibration control performance when pressure fluctuation or flow rate fluctuation of a gas supply source for a gas damper is large during using the gas damper.
The vibration control device equipped with an air intake part 45 and an air damper 43 supporting a building is provided with: a servo-valve 47 for controlling the flow rate of air supplied from the air intake part 45 and supplying air to the air damper 43; a control part 76 for controlling an internal pressure of the air damper 43 through the servo-valve 47, based on position information of the building; and a feed forward part 65 for imparting thrust to the building so as to suppress position fluctuation of the building caused by the pressure fluctuation of air supplied from the air intake part 45.
