Damper device

A damper device comprising:

• a first rotor;
• a second rotor rotatable relative to the first rotor;
• and
• an elastic coupling part configured to elastically couple the first rotor and the second rotor in a rotational direction,
• the elastic coupling part having
• a first torsional characteristic exerted with a first stiffness in a first actuation range of a torsion angle, the first actuation range ranging to both positive and negative sides of the torsion angle, the first actuation range ranging differently on the positive and negative sides of the torsion angle,
• a second torsional characteristic exerted with a second stiffness in a second actuation range of the torsion angle, the second stiffness greater in magnitude than the first stiffness, the second actuation range ranging on the positive side of the first actuation range, and
• a third torsional characteristic exerted with a third stiffness in a third actuation range of the torsion angle, the third stiffness greater in magnitude than the first stiffness, the third stiffness different in magnitude from the second stiffness, the third actuation range ranging on the negative side of the first actuation range.
