摘要： A damper device includes a first rotor, a second rotor, an elastic coupling part elastically coupling the first and second rotors in a rotational direction, and a hysteresis generating mechanism. The hysteresis generating mechanism generates a hysteresis torque and includes a friction member. The friction member is configured to make frictional contact with the first or second rotor. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where torsion is caused from a neutral condition to a first side and a second side in the rotational direction. The friction member makes frictional contact with the first or second rotor so as to generate a hysteresis torque in a second torsion angular range exceeding the first torsion angular range. The friction member is set in a neutral position by actuation of the elastic coupling part in the neutral condition.
