Abstract
A damper device includes damper portions arranged in series with each other in a power transmission path and absorbing torsion by means of elastic force, hysteresis portions arranged in parallel with the damper portions at the power transmission path and absorbing the torsion by means of friction force, an input plate inputting rotational torque into one of the damper portion closest to the input side and the hysteresis portion closest to the input side, an intermediate plate transmitting the rotational torque from the damper portion, arranged at the input side, and the hysteresis portion, arranged at the input side, to the damper portions, arranged at the output side, and the hysteresis portions, arranged at the output side, and an output plate outputting the rotational torque from the damper portion closest to the output side and the hysteresis portion closest to the output side.
