Zusammenfassung:A damper device for transmitting power from a power source therethrough to an output-side member is disclosed. The damper device includes an input-side rotor, an output-side rotor, a plurality of elastic members, an intermediate rotor and a hysteresis generating mechanism. The input-side rotor and the output-side rotor are rotatable relative to each other. The plurality of elastic members elastically couple the input-side rotor and the output-side rotor in a circumferential direction. The intermediate rotor is rotatable relative to the input-side rotor and the output-side rotor, and actuates at least two of the plurality of elastic members in series. The hysteresis generating mechanism includes a friction member slidable in contact with the input-side rotor, the output-side rotor and the intermediate rotor, and generates a hysteresis torque in elastic deformation of the plurality of elastic members.
