摘要:
A damper device, disposed between an engine and a drive unit, includes an input rotor, an output rotor, an elastic coupling part, and a hysteresis torque generating mechanism. The hysteresis torque generating mechanism generates a hysteresis torque together with the input rotor or the output rotor therebetween. The damper device is in a neutral condition when a torque is not transmitted from both the engine and the drive unit, in a first torsional condition when the torque is transmitted from the engine, and in a second torsional condition when the torque is transmitted from the drive unit. The hysteresis torque generating mechanism is configured not to generate a hysteresis torque when the damper device is in the first torsional condition, and not to generate the hysteresis torque in a first range of torsion angle less than a first angle when the damper device is in the second torsional condition.
