Beschreibung
Zusammenfassung:	A metallic support for an exhaust gas purifying catalyst includes a honeycomb body, an outer cylinder, and an intermediate cylinder interposed between the honeycomb body and the outer cylinder. The intermediate cylinder has flexible portions disposed on at least one of ends thereof at predetermined intervals in series in a circumferential direction thereof, and the flexible portions are joined to one of the honeycomb body and the outer cylinder. Thus, the flexible portions are made deformable in directions reducing and enlarging the intervals, and the expansion and contraction forces of the honeycomb body and the outer cylinder are absorbed by the deformations of the flexible portions. Consequently, it is possible to prevent thermal stress from generating in the honeycomb body. Thus, breakage of the honeycomb body has been prevented further reliably.
