PROBLEM TO BE SOLVED: To provide a damper which facilitates the arrangement work of a buffer material and the inspection and maintenance works and which does not require to arrange the buffer material on the whole inner wall faces of a hollow part or a hollow structure and further, which has a specified vibration- resistant and absorptive capacity and which is lighter than conventional dampers. SOLUTION: This vibration control chain damper is suspended in the inside of a hollow part of a building or in the inside of a hollow structure to attenuate the vibration of the building. A buffer material 10 is extended at the outer periphery in the axial direction of the chain 14 without sticking a buffer material in the hollow part of a structure or on the inner wall of a hollow structure. The buffer material 10 is constituted of the exterior layer 13 arranged opposite to the hollow part or the inner wall of the hollow structure, the interior layer 11 arranged opposite to the chain, and the intermediate layer 12 arranged between the exterior and interior layers. And further, an air bubble member layer in which a plurality of independent air bubbles are mixed, is contained in the intermediate layer. |
