ATTENUATION DAMPER
To provide an attenuation damper capable of attenuating rocking in two or more directions and suppressing vibrations of an external structure with respect to micro vibrations such as traffic vibrations.SOLUTION: An attenuation damper 40 has a lower plate 42 that can be fixed to a first external structure, an upper plate 41 that has a projecting portion 12 including at least four corner portions and side portions on a side surface, and an attenuating member 44 that connects the lower plate and the upper plate 41. A second external structure arranged above the upper plate 41 is provided with a plurality of stoppers 46 which do not abut on the corner portions. The respective side portions of the projecting portion 12 correspond to the plurality of stoppers 46. The projecting portion 12 is disposed to have a horizontal clearance and a vertical clearance between the projecting portion 12 and the second external structure. When the projecting portion 12 is relatively displaced with respect to the stoppers 46, the side portions of the projecting portion 12 and the side surfaces of the stoppers 46 abut on each other.SELECTED DRAWING: Figure 5
【課題】２以上の方向の揺れを減衰することができ、交通振動等の微振動に対する外部の構造体の振動を抑制できる原摺ダンパーを提供すること。【解決手段】減衰ダンパー４０は、第１外部構造体に固定可能な下部プレート４２と、側面に少なくとも４つの角部と辺部とを含む凸部１２を有する上部プレート４１と、下部プレートと上部プレート４１を繋ぐ減衰部材４４と、を有し、上部プレート４１の上方に配置される第２外部構造体には、角部に当接しない複数のストッパー４６が設けられており、凸部１２の辺部のそれぞれは、複数のストッパー４６にそれぞれ対応し、凸部１２が第２外部構造体との間に水平隙間及び鉛直隙間を有するように配置され、凸部１２がストッパー４６に対して相対変位する際に、凸部１２の辺部とストッパー４６の側面とが当接する。【選択図】図５
