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).
