Abstract
A dynamic damper is coupled to an intermediate member of a damper device. A drive member of the damper device has additional abutment portions coupled to end portions of vibration absorption springs of the dynamic damper before both first and second inter-element stoppers operate. The second inter-element stoppers operate before the first inter-element stoppers operate and at least by the time when the additional coupling portions are coupled to end portions of the vibration absorption springs. Outer springs and the vibration absorption springs act in parallel to transfer torque after the additional coupling portions are coupled to end portions of the vibration absorption springs.
