Beschreibung
Zusammenfassung:	A cylindrical body of a catalyst container has that overlapped portion of a rolled sheet of metal which is welded in an axial direction of the cylindrical body. A coned portion is welded, at a large diameter portion thereof, to each axial end of the cylindrical body. The large diameter portion of the coned portion has a flange which extends radially outward, and the axial end of the cylindrical body is brought into abutment with an outward end surface of the flange and is fillet-welded along an outer corner which is formed by the flange and the cylindrical body. A heat shield cover is mounted under the casing by connecting a second flange connected to a front end of a downstream exhaust gas pipe to a first flange connected to a rear end of the casing. The heat shield cover is made up of a mounting flange portion and a cover portion. The mounting flange portion is extended so as to abut with an upstream surface of a lower part of the first flange. The cover portion is bent backward and forward to cover the bottom surfaces of the rear coned portion and the first and second flanges. The heat shield cover is connected to the first and second flanges with bolts and nuts by inserting the bolts from the side of the mounting flange portion.
