Abstract

See full text

A damper device includes a first rotor, a second rotor, an elastic coupling part having first and second elastic members, and a hysteresis generating mechanism. The hysteresis generating mechanism includes a friction member, and generates a hysteresis torque. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where the torsion is caused between the first and second rotors by a first torsion angle from a neutral condition, makes frictional contact with the first or second rotor in a second torsion angular range exceeding the first torsion angle so as to generate the hysteresis torque, and does not make frictional contact with the first and second rotors in a predetermined torsion angular range within the second torsion angular range. In the neutral condition, the friction member is set in a neutral position by actuation of the elastic coupling part.
