Abstract
An object of the present invention is to provide a vibration damping device including an instability preventing means, for efficiently suppressing amplification of vibration of a long structure, which is mechanically flexible, due to a resonance phenomenon. A vibration damping device () for reducing vibration of a long structure () includes a displacement amplifier () and limiting members (). The displacement amplifier () is arranged along a given position in the longitudinal direction of the structure (). The displacement amplifier () amplifies a displacement of the structure (). The limiting members () control displacement amplification performed by the displacement amplifier () such that the displacement of the structure () amplified by the displacement amplifier () does not become greater than a first displacement, the first displacement being a displacement of the structure () by which the structure () is not allowed to return to the equilibrium position of the vibration.
