Abstract: An exhaust gas treatment device (1), for an exhaust system (1) of an internal combustion engine, includes a housing (2), providing an exhaust path (3), an injector (4) arranged on the housing (2) for introducing a reduction agent into an exhaust gas flow following the exhaust gas path (3), and a mixer (7) arranged in the housing (2). The mixer (7) includes a shell (8), which encloses a mixer cross section (10) through which the exhaust gas flow can flow. The mixer (7) includes multiple guide blades (11), which on a shell inside project from the shell (8) and project into the mixer cross section (10). A simplified producibility is obtained with the mixer (7) including multiple straps (13), on a shell outside (14), which project from the shell (8) and project into a strap opening (16) formed on the housing (2) and penetrate a housing wall (15).

Abstract: The present invention relates to an exhaust gas treatment device (1), in particular for an internal combustion engine, preferably in a motor vehicle, comprising a housing (2) as well as a substrate body (3) which is situated therein and through which exhaust gases can flow in an axial direction (5). The substrate body (3) is supported axially on the housing (2) via an axial bearing (8) on at least one axial end face (11). To improve the axial support of the substrate body (3), the axial bearing (8) has a supporting ring (10) mounted on the housing and having a U-shaped profile (12), which is open axially toward the end face (11). A bearing ring (17) made of bearing material engages into the U-shaped profile (12) of the supporting ring (10) on its axial end, which faces away from the substrate body (3) and is supported thereon axially. With its axial end facing the substrate body (3), the bearing ring (17) is supported on the end face (11).
