To easily and accurately correct the rotation imbalance of a damper device including a rotation inertial mass damper.SOLUTION: A damper device includes: a plurality of rotating elements including an input element transmitted with torque from an engine, and an output element; an elastic body for transmitting the torque between the input element and the output element; and a rotation inertia mass damper having a mass body which rotates in response to the relative rotation of any two of the plurality of rotating elements. Any of the plurality of rotating elements include two pieces of plate members which oppose each other along an axial direction of the damper device, and are connected to each other so as to grip the other rotating element. The two pieces of plate members have a plurality of balance weight attachment parts which can be attached with balance weights from the outside in an axial direction.SELECTED DRAWING: Figure 3 【課題】回転慣性質量ダンパを含むダンパ装置の回転アンバランスを容易かつ精度よく修正可能にする。【解決手段】ダンパ装置は、エンジンからのトルクが伝達される入力要素および出力要素を含む複数の回転要素と、入力要素と出力要素との間でトルクを伝達する弾性体と、複数の回転要素の何れか２つの相対回転に応じて回転する質量体を有する回転慣性質量ダンパとを含み、複数の回転要素の何れかは、ダンパ装置の軸方向に沿って互いに対向すると共に他の回転要素を挟み込むように連結される２枚のプレート部材を含み、２枚のプレート部材の各々は、軸方向における外側からバランスウェイトを取り付け可能な複数のバランスウェイト取付部を有する。【選択図】図３
