PURPOSE: To provide a hanger bolt vibration restricting body capable of restricting vibration of a hanger bolt, preventing deformation or damage of the hanger bolt and restricting oscillation of a hanging structure.CONSTITUTION: This invention relates to a hanger bolt vibration restricting body constituted in such a way that a hanging structure is fixed to a hanger bolt hung from a ceiling body and fixed so as to hung it down and a vibration load acting on the hanger bolt is reduced to restrict vibration. The vibration restricting body is made of resilient plate-like material, at least an upper part of the plate-like material is abutted against the lower surface of the ceiling body, a part or all of the plate-like material from the upper part to the lower part are abutted against three or more locations at the outer periphery of the hanger bolt and the center of the hanger bolt is positioned to be included in a polygonal shape formed by the three or more abutting locations, and when the vibration energy is inputted to the hanger bolt, a resilient characteristic in the plate-like material realizes a biasing force in an inverted direction of the vibrating direction of the inputted vibration energy to restrict or eliminate the vibration energy.SELECTED DRAWING: Figure 1 |
