Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas shield which can form an anti-leakage and small volume device and which can greatly reduce impingement of exhaust gas against a seal and a support system for catalyst. SOLUTION: An exhaust gas disposal device for an internal combustion engine includes a substantially cylindrical base member 18 swaged within a one-piece housing, and seal systems 22, 24. The one-piece housing includes an inlet which is formed from a single pipe for supporting the base member 18, by spinning and sectioning, and an outlet gas shield diffuser 26a. The spun inlet and the outlet gas shield diffuser have a sectioned arrangement having a plurality of concave and convex parts which are formed during spinning of the housing. The exhaust disposal device can be assembled without the necessity of any high temperature work such as welding.
