Abstract
A damper device for transmitting power 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 first hysteresis generating mechanism. The input-side rotor, to which the power is inputted, is disposed to be rotatable. The output-side rotor is rotatable relative to the input-side rotor. The plurality of elastic members are configured to elastically couple the input-side rotor and the output-side rotor in a circumferential direction. The intermediate rotor is configured to actuate at least two of the plurality of elastic members in series. The intermediate rotor is rotatable relative to the input-side rotor and the output-side rotor. The first hysteresis generating mechanism is configured to apply a hysteresis torque to the intermediate rotor in elastic deformation of the plurality of elastic members.
