Abstract

A damper device includes an input element; an intermediate element; art output element; a first elastic body that transmits a torque between the input element and the intermediate element; and a second elastic body that transmits a torque between the intermediate element and the output element. The damper device also includes a rotary inertia mass damper that includes a first mass body rotating in accordance with relative rotation between the input element and the output element and that is arranged between the input element and the output element to be parallel to a torque transmission path including the first elastic body, the intermediate element and the second elastic body. Finally, the damper devices includes a second mass body; and an elastic body arranged to couple the second mass body with the output element.
