Damper device

A damper device comprising:

• a first rotating body;
• a second rotating body;
• a coil spring interposed in a circumferential direction between the first rotating body and the second rotating body, the coil spring having a first end and a second end each supported to the first and second rotating bodies, orienting a direction along a spring central axis, which is a center of winding, toward the circumferential direction;
• and
• a resin spring seat having a metallic core member inside, the resin spring seat being attached to one of the first and second rotating bodies, in a state in which the first and second ends of the coil spring are supported in the direction along the spring central axis,
• the resin spring seat comprising:
• a seat portion having a spring seating surface on which are seated the first and second ends of the coil spring in a direction along the spring central axis, and an overhang portion that is formed extending in a direction of the spring central axis along an outer perimeter part of the seat portion,
• the metallic core member comprising a metallic core seat part provided along the spring seating surface in the seat portion and provided with a metallic core exposed portion, in which the metallic core seat part is exposed so as to be capable of abutting the coil spring, the metallic core exposed portion being provided on a portion of the spring seating surface which slides against the coil spring,
• the metallic core exposed portion being disposed in at least one of
• a radial inner region of the spring seating surface located radially inward of the spring central axis with respect to a center of rotation of the first and second rotating bodies, and
• a radial outer region of the spring seating surface located radially outward of the spring central axis, with respect to the center of rotation of the first and second rotating bodies, and
• the metallic core member including a coated region in which the metallic core seat part is coated by resin in regions other than the metallic core exposed portion.
