PROBLEM TO BE SOLVED: To provide a dynamic damper capable of obtaining a vibration suppression effect of a vibration control object, even in a case where the damper is applied to the vibration control object whose natural frequency varies.SOLUTION: A dynamic damper D comprises a lever 1 capable of oscillating around a fulcrum O, a weight M mounted on the lever 1 in an axially movable and fixable manner, a spring 2 configured to support the lever 1. In the dynamic damper D, even when a natural frequency of a vibration control object varies, a natural frequency of the dynamic damper D is consistent with the above natural frequency, thereby obtaining a vibration control effect.SELECTED DRAWING: Figure 2

    【課題】固有振動数が変化してしまう制振対象に適用されても制振対象の振動抑制効果が得られるダイナミックダンパの提供である。【解決手段】本発明のダイナミックダンパDでは、支点Oを中心に揺動可能なレバー1と、レバー1に軸方向移動かつ固定可能に装着される錘Mと、レバー1を支持するばね2とを備えて構成されている。本発明のダイナミックダンパDでは、制振対象の固有振動数が変化してもダイナミックダンパD自身の固有振動数を一致させて、制振効果が得られる。【選択図】図2
