Patent ID: 8272966

Claim:
A damper device comprising: a damper portion for absorbing a torsion by use of an elastic force; and a limiter portion generating a slide when the torsion is not absorbed by the damper portion, and the limiter portion including: a first constitutive member formed so as to cover at least one of the damper portion and the limiter portion; a first friction material fixed to one surface of a second constitutive member of the damper portion; a second friction material fixed to the other surface of the second constitutive member of the damper portion; a cover plate provided so as to be slidable to the first friction material, the cover plate being a single plate; 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; a coned disc spring provided between the support plate and the pressure plate in order to bias the pressure plate toward the second friction material, wherein the first constitutive member is at least one of the cover plate and the support plate; and wherein the limiter portion is set so as to be further outward than the damper portion in a radial direction of the damper device, and the first constitutive member includes a radially inner portion extending so as to be further inward than a sliding surface of the limiter portion in the radial direction of the damper device, and the damper portion is covered by the radially inner portion of the first constitutive member.
