Abstract
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.
Claims6
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 section and integrally rotate with the second member in a second section;
- 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.
