Abstract:
A damper device has a dynamic damper that includes a mass body and vibration absorption springs that couple the mass body and an intermediate member to each other. The vibration absorption springs are arranged side by side with outer springs in the circumferential direction. The mass body has spring abutment portions that abut against end portions of the vibration absorption springs. The intermediate member has first outer spring abutment portions that abut against end portions of the outer springs and second outer spring abutment portions that abut against end portions of the vibration absorption springs on the radially inner side with respect to the spring abutment portions. The first outer spring abutment portions extend toward the radially outer side with respect to the second outer spring abutment portions.
