Abstract

An exhaust gas flap, especially for the exhaust gas stream of an internal combustion engine, includes a flap tube (22) and a flap diaphragm (24) carried in an interior of the flap tube on a pivot shaft (16) rotatable about a pivot axis. A flap wing (28, 30) is mounted on the pivot shaft (16) and a wing stop (32, 34) is associated with the flap wing (28, 30) on an inner circumferential area of the flap tube. The flap wing (28, 30) has a mounting area (56, 58) with uncurved mounting surfaces (60, 64). Opposing mounting surfaces (62, 66) or/and a mounting recess (52, 54) at the pivot shaft (16) provide an opposing mounting area that at least partially receives the flap wing mounting area (56, 58) of the flap wing (28, 30), the opposing mounting area being provided on the outer circumferential area of the pivot shaft (16).
