Abstract

Official abstract text for this publication.

In a damper device according to an embodiment, a third member is configured to be rotatable about a rotation center, rotate integrally with a first member in a first section, and rotate integrally with a second member in a second section. A first friction member has a first friction face that generates a friction torque along with relative rotation of the first member and the second member, and a second friction member has a second friction face that generates a friction torque along with relative rotation of the second member and the third member.

First claim

Opening claim text (preview).

The invention claimed is: 1. A damper device comprising: a first member rotatable about a rotation center; a second member rotatable about the rotation center; a third member configured to be rotatable about the rotation center and integrally rotate with the first member in a first torsion angle range of the damper device and integrally rotate with the second member in a second torsion angle range of the damper device; a first resilient member that resiliently expands and contracts along with relative rotation of the first member and the second member about the rotation center; a first friction member having a first friction face that generates a friction torque along with the relative rotation of the first member and the second member; and a second friction member having a second friction face that generates a friction torque along with relative rotation of the second member and the third member, wherein one of the first member and the third member is provided with a hook, and in the first torsion angle range of the damper device the hook circumferentially catches the other of the first member and the third member to integrally rotate the first member and the third member, and in the second torsion angle range of the damper device, the hook does not circumferentially catch the other of the first member and the third member, and the second member and the third member are integrally rotated by a frictional force between the second member and the third member. 2. The damper device according to claim 1 , further comprising a second resilient member that presses the second member and the third member onto the second friction face. 3. The damper device according to claim 1 , wherein the first friction member further has a third friction face that generates a friction torque along with relative rotation of the second member and the third member. 4. The damper device according to claim 3 , further comprising a second resilient member that presses the second member and the third member onto the second friction face, wherein the second resilient member further presses the second member and the third member onto the third friction face. 5. A damper device comprising: a first member rotatable about a rotation center; a second member rotatable about the rotation center; a third member configured to be rotatable about the rotation center and rotate integrally with the first member in a first torsion angle range of the damper device and rotate integrally with the second member in a second torsion angle range of the damper device; a fourth member configured to be rotatable about the rotation center relative to the integrally rotated first member, second member, and third member in a third torsion angle range of the damper device, the second torsional angle range being greater than the third torsional angle range and less than the first torsion angle range; a first resilient member that resiliently expands and contracts along with relative rotation of the first member and the second member about the rotation center; a third resilient member that resiliently expands and contracts along with relative rotation of the second member and the fourth member about the rotation center; a first friction member having a first friction face that generates a friction torque with the relative rotation of the first member and the second member; a second friction member having a second friction face that generates a friction torque along with the relative rotation of the second member and the third member; and a third friction member having a fourth friction face that generates a friction torque with the relative rotation of the first member and the fourth member.
