Abstract
An exhaust-gas flap device, including for the exhaust-gas flow of an internal combustion engine, has a flap pipe and a flap plate that is supported in the interior of the flap pipe on a pivot shaft. The pivot shaft is rotatable about a pivot axis (A). The pivot shaft has first and second axial end regions and is supported rotatably on the flap pipe by respective first and second bearing assemblies. The pivot shaft is configured, in the first axial end region, for coupling to a drive element of a pivot drive. The pivot shaft is, in at least one of the axial end regions, in contact with vibration-damping material that is supported relative to the flap pipe.
