To provide a damper device which includes a vibration damping element utilizing contact friction between a spring and a plate material and a spring element utilizing a spring and makes vibrations less likely to occur in vibration damping characteristics even if an anteroposterior angle of a vibration inhibition object is changed.SOLUTION: A damper device includes: a housing 50 attached to a vibration inhibition object; a pendulum 72 which is rotatably attached to a support shaft 66 in the housing 50 and vibrates in a vibration direction of the vibration inhibition object; a first spring 74A which is fixed to one inner surface of the housing 50 at one end and contacts with one side surface of the pendulum 72; and a second spring 74B which is fixed to the other inner surface of the housing 50 at one end and contacts with the other side surface of the pendulum 72.SELECTED DRAWING: Figure 2
【課題】バネと板材との接触摩擦による振動減衰要素とバネによるバネ要素とを備えると共に、振動抑制対象の前後方向の角度が変わっても、振動減衰特性にばらつきが生じにくいダンパー装置を提供する。【解決手段】ダンパー装置は、振動抑制対象に取り付けられた筐体50と、筐体50内の支軸66に回転自在に取り付けられ、振動抑制対象の振動方向に沿って振動する振り子72と、一端が筐体50の一方の内側面に固定され、且つ、振り子72の一方の側面に接触する第1バネ74Aと、一端が筐体50の他方の内側面に固定され、且つ、振り子72の他方の側面に接触する第2バネ74Bとを有する。【選択図】図2
