Abstract
A damper device is disclosed. The damper device includes first and second side plates opposed in an axial direction, a hub flange, elastic members, a first friction member, and an oil supply portion. The first and second side plates has an annular shape. The hub flange, including a boss portion and a flange portion, is rotatable relative to the first and second side plates. The flange portion is disposed between the first and second side plates in the axial direction. The elastic members elastically couple the hub flange and both the first and second side plates in a rotational direction. The first friction member is disposed between the first side plate and the flange portion in the axial direction, and generates friction resistance when the first side plate and the hub flange rotate. The oil supply portion supplies lubricating oil from the second side plate to the first friction member.
