Damper device

A damper device including:

• a plurality of rotating elements including an input element to which torque from an engine is transmitted, and an output element;
• a plurality of first elastic bodies that each transmit torque between the input element and the output element;
• and a rotary inertia mass damper having a mass body that rotates in accordance with relative rotation between a first rotating element that is any of the plurality of rotating elements and a second rotating element that is different from the first rotating element, the damper device comprising:
• 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, wherein
• the rotary inertia mass damper has a planetary gear including a sun gear that rotates as a unit with the first rotating element, a carrier that rotatably supports a plurality of pinion gears and that rotates as a unit with the second rotating element, and a ring gear that meshes with the plurality of pinion gears and that serves as the mass body, and
• 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,
• wherein the plurality of first elastic bodies have a length greater than a length of the second elastic bodies and configured so that the plurality of first elastic bodies have a larger torsional angle than a torsional angle of the plurality of second elastic bodies.
