1. A damper device, comprising:
a first rotor;
a second rotor rotatable relative to the first rotor;
a plurality of elastic members circumferentially aligned, the plurality of elastic members configured to elastically couple the first rotor and the second rotor in a rotational direction;
an intermediate member disposed axially between the first rotor and the second rotor so as to be rotatable relative to the first rotor and the second rotor; and
a hysteresis generating mechanism disposed axially between the first rotor and the second rotor, the hysteresis generating mechanism configured to generate a hysteresis torque in relative rotation between the first rotor and the second rotor,
wherein the intermediate member includes an annular portion and a support portion,
the annular portion is provided radially outside the plurality of elastic members,
the support portion protrudes radially inward from the annular portion, the support portion disposed between at least circumferentially adjacent two of the plurality of elastic members, the support portion configured to actuate the at least circumferentially adjacent two of the plurality of elastic members in series,
the first rotor includes a first input plate and a second input plate, the first and second input plates each having a disc shape, the first and second input plates axially opposed to each other, the first and second input plates fixed to each other,
the second rotor includes a flange disposed axially between the first input plate and the second input plate, and
the intermediate member comprises
a first intermediate plate disposed axially between the first input plate and the flange, and
a second intermediate plate disposed axially between the second input plate and the flange, the second intermediate plate fixed to the first intermediate plate by a fastener at the support portion of the intermediate member so as to be immovable with respect thereto in both axial and rotational directions.
