Document Type and Number:
Japanese Patent JP6928820
Kind Code:
B2
Abstract:
A damper device includes a plurality of rotational elements including an input element and an output element; an elastic body that transmits a torque between the input and the output elements; and a rotary inertia mass damper with a mass body rotating in accordance with a relative rotation between a first rotational element which is one of the rotational elements and a second rotational element different from the first rotational element. The rotary inertia mass damper includes a sun gear that rotates integrally with the first rotational element, pinion gears rotatably supported by the second rotational element, and a ring gear that meshes with the pinion gears and works as the mass body. The second rotational element includes a plurality of ring gear supporting portions arranged at intervals in a circumferential direction so as to restrict a movement of the ring gear in an axial direction of the damper device.
