Abstract
A damper includes a first, second, and third rotation member rotatable around a rotation axis, a first elastic portion interposed between the first rotation member and the second rotation member and elastically deformed by a relative rotation between the first rotation member and the second rotation member, a second elastic portion interposed between the second rotation member and the third rotation member and elastically deformed by a relative rotation between the second rotation member and the third rotation member, and a dynamic vibration absorber. The dynamic vibration absorber includes a rolling element that is positioned at an inner side relative to the first elastic portion and the second elastic portion in a radial direction of the rotation axis, and is rotatable relative to the second rotation member.
