Abstract
An exhaust gas flap includes a flap tube (12), a flap diaphragm (16) carried in the interior of the flap tube (12) on a pivot shaft (14) rotatable about a pivot axis (A), a pivot drive (30) and a coupling device (36) coupling the pivot shaft (14) to a drive shaft (34) of the pivot drive (30). The coupling device (36) includes a first coupling area (42) that positive-lockingly meshes with the drive shaft (34) and a second coupling area (44) that positive-lockingly meshes with the pivot shaft (14). A biasing element (78) is supported in relation to the coupling device (36) and is supported in relation to one shaft of the drive shaft (34) and the pivot shaft (14). The coupling device (36) is axially biased by the biasing element (78) towards the other shaft and is prestressed about the pivot axis in relation to the one shaft.
