Abstract:
1. A damper mechanism for transmitting torque and for absorbing and damping torque fluctuations, comprising: a first rotating member; a second rotating member being configured and arranged to be relatively rotatable with respect to the first rotating member; a third rotating member being configured and arranged to be relatively rotatable with respect to the second rotating member; a first damper having a plurality of first elastic members elastically coupling the first rotating member and the second rotating member in the rotation direction; and a second damper elastically coupling the second rotating member and the third rotating member in the rotation direction, and being configured to begin operating at a torque that is lower than the minimum operating torque of the first damper, a plurality of first spring seats being sandwiched between ends of the first elastic members and the second rotating member, the second rotating member having a plurality of support components that support the ends of the first elastic members in the rotation direction, the plurality of support components supporting the first elastic member in a state of being compressed in the rotation direction, the first rotating member having a plurality of contact components disposed at locations corresponding to the support components in the rotation direction and configured to come into contact with the ends of the first elastic members, and a sliding component that is disposed on the outer peripheral side of the first elastic members and supports the first elastic members in the radial direction, gaps being formed in the rotation direction between the contact components and the ends of the first elastic members.
