PURPOSE: To provide a dynamic damper by which the durable life of each damper can be set to approximately the same. CONSTITUTION: When large and small natural frequencies fd1 -fd3 for respective frequency bands of a plurality of dampers composing a dynamic damper 4 are set, not only moment of inertia Id1 -Id3 , but also the values of the dynamic spring constants K1 -K3 of respective dampers 9a-9c are set within a range of approximately±10%, and also the dynamic spring constants K1 -K3 are regulated. Hereby, the maximum values of the twist amplitude of each dampers 9a-9c are made not to be largely sprinkled as the conventional case by equalizing rubber distortion for respective dampers 9a-9c.
