PROBLEM TO BE SOLVED: To enhance vibration proof of a building having an opening part, in a damping device. SOLUTION: In a building 10, the damping device 13 for operating so as to damp vibration in the X direction, is arranged in the opening part 12 of a parking garage. This vibration damping device 13 is composed of a rotary door 14 for opening or closing the opening part 12, and a damping unit 18 (indicated by a broken line in the Fig. 1) arranged in an inside space of the rotary door 14. The damping device 13 operates so as to damp swinging in the X direction of the building 10 by being firmly joined to the building 10 when the rotary door 14 is put in a state of closing the opening part 12. Thus, when the vibration in the X direction is inputted to the building 10, since the damping unit 18 incorporated into the rotary door 14 performs damping operation, the vibration proof of the building 10 is improved. Thus, the vibration proof of the building 10 having the opening part 12 in a first floor part, can be improved. COPYRIGHT: (C)2007,JPO&INPIT
