ABSTRACT:
Catalytic converter (2) includes a catalyst container (10) formed from a tubular blank (10′) and having a catalyst carrier, and a flange member (11) joined to the hollow member. The tubular blank (10′) is subjected to a spinning operation by forming roll or rolls (22A), to form the catalyst container (10) having a desired shape, and the opposed circumferential surfaces of the catalyst container (10) and flange member (11) are forced against each other by the forming roll or rolls (22A) or an array of presser pieces (22B) while the catalyst container and flange member are rotated relatively to each other, so that friction heat is generated for friction-welding the catalyst container and flange member at their joining portions (10b, 11b).
