Abstract
A damper device 10 includes a dynamic damper 30 that has third springs SP3 coupled to an intermediate member 12 and that also has, as a mass body coupled to the third springs SP3, a turbine runner 5, a coupling member 31, etc. The third springs SP3 of the dynamic damper 30 are disposed so as to overlap both in the axial and radial directions of the damper device 10 second springs SP2 that are disposed inward of the first springs SP1 to transfer torque between a drive member 11 and a driven member 15. A plane PL including the axes of the third springs SP3 and perpendicular to the axis of the damper device 10 is included in the range of the thickness of spring contact portions 31c of the coupling member 31 in the axial direction of the damper device 10.
