Damper device

A damper device comprising:

• first and second side plates each having an annular shape, the first and second side plates opposed to each other in an axial direction, the first and second side plates each including an opening in a center part thereof;
• a hub flange rotatable relative to the first and second side plates, the hub flange including a boss portion and a flange portion, the flange portion extending radially outward from the boss portion, the flange portion disposed between the first and second side plates in the axial direction;
• a plurality of elastic members elastically coupling the hub flange and both the first and second side plates in a rotational direction;
• a first friction member disposed between the first side plate and the flange portion in the axial direction, the first friction member configured to generate friction resistance when the first side plate and the hub flange are rotated relative to each other;
• and
• an oil supply portion provided in the flange portion radially inward from an inner peripheral edge of the first friction member, the oil supply portion configured to supply a lubricating oil from the second side plate to the first friction member through the flange portion.
