Abstract
A damper device includes a first plate member rotated when the rotational force is inputted from an input side, a second plate member rotatable relative to the first plate member and outputting the rotational force to an output side when rotated in response to rotation of the first plate member, a damper portion for absorbing relative rotation between the first plate member and the second plate member, and a hysteresis portion for absorbing the relative rotation by a friction force. The hysteresis portion includes an intermediate member between the first plate member and the second plate member, and the intermediate member is pressed against one of the first plate member and the second plate member by the other one of the first plate member and the second plate member when the first plate member and the second plate member rotate relative to each other.
