A damper includes a first rotation member being rotatable around a rotation axis, a second rotation member being rotatable around the rotation axis, a third rotation member being rotatable around the rotation axis, a first elastic portion interposed between the first rotation member and the second rotation member and being 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 being elastically deformed by a relative rotation between the second rotation member and the third rotation member, and a dynamic vibration absorber including 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, the rolling element being rotatable relative to the second rotation member. |
