Summary:To suppress the excessive displacement beyond assumption of a weight member absorbing vibrations of a building, with a simple structure.SOLUTION: A vibration control device 1 includes a frame 10 that can be installed in a structure, a weight member 30 that is supported so as to move in one horizontal direction (X-axis-direction) inside the frame 10, and a spring member 40 that couples the weight member 30 and the frame 10, and in which a spring constant between the weight member 30 and the frame 10 changes from a first value to a second value larger than the first value when the displacement of the weight member 30 exceeds a predetermined threshold value.SELECTED DRAWING: Figure 1 【課題】建物の振動を吸収する錘部材の想定以上の過大変位を簡易な構成で抑制する。【解決手段】制振装置１は、構造物に設置可能なフレーム１０と、フレーム１０の内側において水平な一方向（Ｘ軸報告）に移動可能に支持される錘部材３０と、錘部材３０とフレーム１０とを連結し、錘部材３０の変位が所定の閾値を超えた場合に錘部材３０とフレーム１０との間のばね定数が第１値から第１値より大きい第２値に変化するばね部材４０と、を備える。【選択図】図１
