Patent ID: 8282494

Claim:
A damper device inputting torque of a power source from an input side and outputting the torque to an output side, the damper device comprising: a plurality of damper portions arranged in series with each other in a power transmission path and absorbing torsion by means of elastic force: a plurality of hysteresis portions arranged in parallel with the plurality of 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 among the plurality of damper portions and the hysteresis portion closest to the input side among the plurality of hysteresis portions; 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, at a position between the damper portion closest to the input side and the damper portion closest to the output side and between the hysteresis portion closest to the input side and the hysteresis portion closest to the output side; an output plate outputting the rotational torque from the damper portion closest to the output side among the plurality of damper portions and the hysteresis portion closest to the output side among the plurality of damper portions; a limiter portion sliding when a torsion reaches a level where the torsion is not absorbed by the damper portions and the hysteresis portions in the power transmission path; and wherein the limiter portion is arranged to be closer to the output side than the damper portion closest to the output side among the plurality of damper portions and the hysteresis portion closest to the output side among the plurality of hysteresis portions, in the power transmission path.
