Abstract: The present invention relates to an exhaust gas treatment device for an exhaust system of a combustion engine, more preferably of a motor vehicle with a housing comprising a jacket and an outlet funnel, with at least one exhaust gas treatment element which is arranged in the jacket and which via a support ring is axially supported on the housing, wherein the outlet funnel comprises an outer funnel and an inner funnel. A simplified design is obtained if the outer funnel at an inner end facing the jacket is connected to the jacket in a fixed manner and at an outer end facing away from the jacket is connected in a fixed manner to the inner funnel, and if between the inner funnel and the outer funnel an insulation space circumferentially running in circumferential direction is formed and the inner funnel at an inner end facing the jacket carries the support ring and relative to the outer funnel is at least axially loose.

Abstract: An exhaust gas treatment device for an exhaust gas system of an internal combustion engine, in particular of a motor vehicle, includes a housing and at least one exhaust gas treatment insert arranged in the housing and sheathed by bearing material on the circumference. To improve the axial fixation of the position of the exhaust gas treatment insert in the housing, at least one frictional structure is provided between the bearing material and the housing.
