    摘要: A housing (2) for an exhaust gas-treating device (1) of an exhaust system of an internal combustion engine includes a jacket (6) closed in the circumferential direction for mounting at least one exhaust gas-treating element (5. The jacket passes over at at least one axial end into a ring body (8, 9). The ring body (8, 9) is closed in the circumferential direction. The housing (2) can be connected to another component of the exhaust system. A simplified manufacture is achieved if the jacket (6) and the at least one ring body (8, 9) are manufactured from a single sheet steel billet (10) by rolling the sheet steel billet (10) in the circumferential direction and by connecting abutting edges (11) of the sheet steel billet (10). The jacket (6) and the at least one ring body (8, 9) differ from one another by different materials and/or different wall thicknesses (12, 13, 14).
