Abstract
A damper deviceincludes a dynamic damperthat has third springs SPcoupled to an intermediate memberand that also has, as a mass body coupled to the third springs SP, a turbine runner, a coupling member, etc. The third springs SPof the dynamic damperare disposed so as to overlap both in the axial and radial directions of the damper devicesecond springs SPthat are disposed inward of the first springs SPto transfer torque between a drive memberand a driven member. A plane PL including the axes of the third springs SPand perpendicular to the axis of the damper deviceis included in the range of the thickness of spring contact portionsof the coupling memberin the axial direction of the damper device
