Abstract: A damper device including an input element and an output element; an elastic body transmitting torque between the input element and the output element; and a rotary inertia mass damper having a mass body. The rotary inertia mass damper includes a sun gear, a carrier rotatably supporting pinion gears, and a ring gear that meshes with the pinion gears and serving as the mass body. A pair of washers is located on both sides of each pinion gear axially. The ring gear includes an annulus gear having internal teeth meshing with the pinion gears and a weight body fixed to the annulus gear such that the weight body is in contact with a side surface of the annulus gear. An inner circumferential surface of the weight body is supported in a radial direction by a tip of the pinion gear or an outer circumferential surface of the washer.

Abstract: A damper device includes rotating elements including an input element and an output element, first elastic bodies that each transmit torque between the input element and the output element, a plurality of second elastic bodies that act in parallel with the plurality of first elastic bodies when torque transmitted between the input element and the output element is greater than or equal to a predetermined value, and a rotary inertia mass damper. The rotary inertia mass damper includes a sun gear, a carrier that rotatably supports a plurality of pinion gears, and a ring gear that meshes with the plurality of pinion gears and that serves as a mass body. The plurality of second elastic bodies are located at a different position than the plurality of first elastic bodies in a radial direction of the rotating elements and are circumferentially aligned with the plurality of pinion gears.
