To improve vibration damping properties while achieving long stroke for a damper device using an arc spring.

This damper device 10 includes: a drive member 11 to which power is transmitted from an engine that serves as a prime mover; a first intermediate member 12 to which power is transmitted from the drive member 11 via a first spring SP1; a second intermediate member 14 to which power is transmitted from the first intermediate member 12 via a second spring SP2; and a driven member 15 to which power is transmitted from the second intermediate member 14 via a third spring SP3. Therein, a coil spring is used as the first and second springs SP1, SP2, and an arc spring positioned further toward the inner periphery than the first and second springs SP1, SP2 is used as the third spring SP3.
