Abstract

A valve for an exhaust gas line of an internal combustion engine in which a closure body is arranged in a duct and is positioned in a recess of a shaft, the closure body being pivotable about a rotation axis of the shaft. The closure body has two sides and a circumferential surface arranged between the two sides. The circumferential surface has sections with different external dimensions. A first external dimension of the circumferential surface of the closure body in a first section is smaller than the smallest internal dimension between end regions of the recess of the shaft in which the closure body sits. A second external dimension of the circumferential surface in a second section is greater than the smallest internal dimension of the recess of the shaft. The circumferential surface contacts the shaft in each of the two end regions of the recess.
