To provide a dynamic vibration absorbing device which is configurable inexpensive and simple.SOLUTION: A dynamic vibration absorbing device 1 comprises a support part 3 which is installed in a structure 2, and a pendulum part 4 which is suspended from the support part 3 and performs pendulum motion, and vibration of the structure 2 is reduced by synchronizing a natural period of the pendulum motion of the pendulum part 4 with a natural period of the structure 2. In the dynamic vibration absorbing device, the pendulum part 4 includes a weight 5 and suspending materials 6 connecting the support part 3 with the weight 5. The suspending materials 6 include: a first suspending material 61 which is connected to the support part 3 rotatably around a first axis 71a extending in a first horizontal direction; and a lower suspending material 62 which is connected to the upper suspending material 61 rotatably around a second axis 72a extending in a second horizontal direction crossing the first horizontal direction and to which the weight 5 is connected.SELECTED DRAWING: Figure 1
【課題】安価で簡便な構成とすることができる動吸振装置を提供する。【解決手段】構造物２に設置された支持部３と、支持部３に吊り下げられて振り子運動する振り子部４と、を有し、振り子部４の振り子運動の固有周期を構造物２の固有周期に同調させて構造物２の振動を低減させる動吸振装置１において、振り子部４は、錘５と、支持部３と錘５とを連結する吊り材６と、を有し、吊り材６は、支持部３に第１水平方向に延びる第１軸線７１ａ回りに回転可能に連結された上吊り材６１と、上吊り材６１に第１水平方向と交差する第２水平方向に延びる第２軸線７２ａ回りに回転可能に連結され、錘５が連結された下吊り材６２と、を有する。【選択図】図１
