Abstract
A damper device is provided with a first rotating body, a second rotating body, a coil spring and a spring seat. The coil spring is interposed in a circumferential direction between the first and second rotating bodies. The resin spring seat includes a seat portion, an overhang portion and a pair of clamping protrusions. The overhang portion extends in the circumferential direction from an outer diameter end of the seat portion and covers an outer diameter side of the coil spring. The clamping protrusions protrude from the seat portion and sandwich an attaching portion of the one of the rotating bodies. The clamping protrusions are relatively turnable in a radial direction of the rotating bodies. The clamping protrusions have a low-rigidity portion on an outer diameter direction side of the spring central axis and a high-rigidity portion on an inner diameter direction side of the spring central axis.
