  With the recent increase in size and height of structures, the effects of vibrations on structures such as buildings have increased, and there is a gap between swing systems composed of suspended objects and materials and structures such as buildings. In the case where resonance occurs, it is required to quickly suppress the growth of the swing of the suspended object. In particular, when a large suspended object (for example, a large chandelier) is suspended from a high position in a large facility, the suspended object shakes greatly in the horizontal direction, giving fear to the person under the suspended object. Therefore, it is necessary to reliably suppress the swinging of the suspended object in the horizontal direction.

It is possible to absorb efficiently and to reliably suppress the swinging of the suspended object. Further, since the damping means can be arranged on the suspended object support portion side, the attenuation means can be maintained with the suspended object lowered, and the maintenance work is facilitated.

In addition, it is preferable to further include alignment means for moving the connected portion in the horizontal direction so that the connecting portion and the connected portion are aligned with respect to the vertical axis.
By adopting such a configuration, when the hanger is raised, the connecting portion of the connecting / disconnecting means and the connected portion can be reliably connected, and the aligning means is arranged on the hanger supporting portion side. Therefore, the alignment means can be maintained while the suspended object is lowered, and the maintenance work is facilitated.

In addition, it is preferable that the alignment means is a first and a second tension spring that pulls the connected parts together.
