摘要： A damper device includes a plurality of rotational elements, a plurality of elastic bodies, a rotary inertia mass damper and a housing that houses the plurality of rotational elements, the plurality of elastic bodies and the rotary inertia mass damper, the housing including a front cover. The rotary inertia mass damper is configured to include a planetary gear that includes a sun gear, a plurality of pinion gears, and a carrier that rotatably supports the plurality of pinion gears. The carrier is centered by either the sun gear or a member that rotates integrally with the sun gear by being radially supported by either the sun gear or the member that rotates integrally with the sun gear. In addition, the carrier is spline-engaged to the front cover when a lockup clutch is engaged.

摘要： A drive member of a damper device includes a first input plate member and a second input plate member that rotatably support a plurality of pinion gears of a planetary gear of a rotary inertia mass damper. A driven member includes an outer teeth gear portion that meshes with the pinion gear in an outer circumferential portion thereof and is disposed between the first and the second input plate members in an axial direction so as to work as a sun gear of the planetary gear. A stopper is configured to restrict the relative rotation between the drive member and the driven member and includes a contact portion arranged in the outer circumferential portion of the driven member so as to contact with the first input plate member.
