Claim:
1. A damper device including an input element, an output element, first elastic bodies that transfer torque between the input element and the output element, and second elastic bodies that are disposed inward of the first elastic bodies to transfer the torque between the input element and the output element, comprising: an intermediate element that is coupled to the input element via the first elastic bodies and coupled to the output element via the second elastic bodies; a dynamic damper having third elastic bodies that are coupled to any of rotary elements forming the damper device between the first elastic bodies and the second elastic bodies, a coupling member having a plurality of elastic body contact portions each contacting an end of a corresponding one of the third elastic bodies, and a mass body that is fixed to the coupling member, wherein the third elastic bodies are disposed so as to overlap the second elastic bodies both in axial and radial directions of the damper device, and a plane including axes of the third elastic bodies and perpendicular to an axis of the damper device is included in a range of a thickness of the elastic body contact portions in the axial direction of the damper device.
