Abstract
A damper mechanism () includes a first flywheel (), an intermediate rotating body () arranged to be rotatable with respect to the first flywheel (), a second flywheel () arranged to be rotatable with respect to the intermediate rotating body (), a first damper () having a plurality of first coil springs () elastically coupling the first flywheel () and the intermediate rotating body () in a rotation direction, and a second damper () elastically coupling the intermediate rotating body () and the second flywheel () in the rotation direction and that begins operating at a torque that is lower than the minimum operating torque of the first damper (). The first coil springs () are accommodated between the first flywheel () and the second flywheel () in a state of having been compressed in the rotation direction.
