Device for cleaning exhaust gases by a metallic catalyst carrier that is installed in an exhaust gas passage and is contained in a metallic outer cylinder, wherein a structure for absorbing a difference in the thermal expansion between the metallic catalyst carrier and the outer cylinder is realized without causing stress to the metallic catalyst carrier and without requiring strict tolerance in production. A cushioning material made of a heat-resistant wire gauze is arranged between the metallic catalyst carrier and the metallic outer cylinder, and the cushioning material, metallic carrier and metallic outer cylinder are conductively joined. The cushioning material is compressed between the metallic catalyst carrier and the outer cylinder, and the cushioning material is joined to the metallic catalyst carrier and to the outer cylinder. Here, the junction is accomplished locally without overlapping one upon the other in the axial direction of the outer cylinder.
