1. 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 with respect to a center rotation of the damper device, the coil spring having first and second in which two ends thereof are supported to the first and second rotating bodies, the first and second ends of coil spring being oriented 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 on which one of the first and second ends of the coil springs are seated in the direction along the spring central axis, andan overhang portion extending in the circumferential direction from an outer diameter end of the seat portion with respect to the center rotation of the damper device and covering an outer diameter side of the coil spring with respect to the center rotation of the damper device, and the metallic core member comprising an overhang metallic core part extending from the overhang portion at an outer diameter direction position on the spring central axis, and the overhang metallic core part comprising a low-rigidity portion that is provided on a side close to the seat portion in the circumferential direction, and a high-rigidity portion that is provided on a side far from the seat portion in the circumferential direction, the high-rigidity portion having a relatively higher rigidity with respect to a relatively lower rigidity of the low-rigidity portion. |
