DYNAMIC VIBRATION ABSORPTION DEVICE
To provide a dynamic vibration absorption device which is excellent in installation workability and whose resonance frequency can be easily adjusted.SOLUTION: A dynamic vibration absorption device 10 is installed on a ceiling 1 comprising two cradlings 2 arranged at an interval from each other and a ceiling board 5 fixed to the lower surface of the cradling 2, and comprises: dynamic vibration absorption members 21 to 23 that have a mass part 24, and an elastic part 25 extending downward from a part of the lower surface of the mass part 24; and a support member 30 that has a pair of attachment parts 31 capable of being attached to each of the two cradlings 2, and an extension part 36 extending between the pair of attachment parts 31, and supports the dynamic vibration absorption members 21 to 23. The extension part 36 has a support surface 36A that receives the lower surface of the mass part 24 with the lower end of the elastic part 25 protruding below the lower surface of the extension part 36.SELECTED DRAWING: Figure 4
【課題】取付けの施工性に優れているとともに、共振周波数の調整が容易である動吸振装置を提供する。【解決手段】動吸振装置１０は、互いに間隔を空けて配列された２本の野縁２と野縁２の下面に固定された天井ボード５とを備えた天井１に設置され、質量部２４と、質量部２４の下面の一部の領域から下方に延びる弾性部２５と、を有する動吸振部材２１〜２３と、２本の野縁２のそれぞれに取り付け可能な一対の取付部３１と、一対の取付部３１の間で延びる延伸部３６と、を有し、動吸振部材２１〜２３を支持する支持部材３０と、を備え、延伸部３６は、弾性部２５の下端が延伸部３６の下面よりも下方に突出した状態で質量部２４の下面を受ける支持面３６Ａを有する。【選択図】図４
