• said housing having an upstream end region adjoining said deflection member;
• at least one exhaust gas treatment unit arranged in said housing and having a shell;
• said housing and said shell conjointly defining an intermediate space therebetween;
• at least one bearing/sealing unit disposed in said intermediate space;
• said at least one bearing/sealing unit having at least two bearing/sealing rings disposed radially one behind the other so as to be nested inside one another, each of said bearing/sealing rings being configured as a formed sheet metal part;
• each of said bearing/sealing rings being configured as an open ring interrupted in a circumferential interruption region;
• and,
• the circumferential interruption region of at least one of said bearing/sealing rings being offset in a circumferential direction with respect to the circumferential interruption region of another one of said bearing/sealing rings.
