DYNAMIC VIBRATION REDUCER AND FLOOR
PROBLEM TO BE SOLVED: To provide a dynamic vibration reducer which inhibits deterioration of a damping performance for floor vibration even when a viscoelastic member which tends to cause creep is used.SOLUTION: A dynamic vibration reducer 1 includes: vibration control plates 20, 21; and a fixing mechanism 40. The vibration control plates 20, 21 have: metal plates 31, 71 including first surface 31A, 71A and second surfaces 31B, 71B; and viscoelastic members 32, 72 which are disposed on the first surfaces 31A, 71A so as to expose parts of the first surfaces 31A, 71A. The fixing mechanism 40 restrains the metal plates 31, 71 in a thickness direction while contacting with exposed portions of the first surfaces 31A, 71A and the second surfaces 31B, 71B.SELECTED DRAWING: Figure 3
【課題】クリープの生じ易い粘弾性部材を用いたときであっても、床振動に対する制振性能の低下を抑制することが可能な動吸振装置を提供する。【解決手段】動吸振装置１は、制振板２０，２１と、固定機構４０と、を備えている。制振板２０，２１は、第１面３１Ａ，７１Ａ及び第２面３１Ｂ，７１Ｂを含む金属板３１，７１と、第１面３１Ａ，７１Ａの一部を露出させるように第１面３１Ａ，７１Ａ上に配置された粘弾性部材３２，７２と、を有している。固定機構４０は、第１面３１Ａ，７１Ａの露出部分及び第２面３１Ｂ，７１Ｂに接触した状態で金属板３１，７１を厚み方向に拘束する。【選択図】図３
