Abstract: A damper device includes a damper portion and a limiter portion, and the limiter portion has a first constitutive member formed to cover the damper portion or the limiter portion, a first and second friction materials fixed to a second constitutive member of the damper portion, a cover plate provided so as to be slidable to the first friction material, a support plate arranged so as to be distant from the cover plate at a radially inner portion of the support plate and so as to contact the cover plate at a radially outer portion of the support plate, a pressure plate provided so as to be slidable to the second friction material and a coned disc spring provided between the support plate and the pressure plate, wherein the first constitutive member is at least one of the cover plate and the support plate.

Abstract: A damper device includes a first plate member rotated when the rotational force is inputted thereto from an input side, a second plate member rotatable relative to the first plate member and outputting the rotational force to an output side when being rotated in response to a rotation of the first plate member, a damper portion for absorbing a relative rotation between the first plate member and the second plate member, and a hysteresis portion for absorbing the relative rotation by a friction force, wherein the hysteresis portion includes an intermediate member between the first plate member and the second plate member, and the intermediate member is pressed against one of the first plate member and the second plate member by the other one of the first plate member and the second plate member when the first plate member and the second plate member rotate relative to each other.
