成であることを特徴とするメタル担体。[Claims for Utility Model Registration] An elliptical honeycomb body formed by stacking and winding a flat plate and a corrugated plate, an inner small-diameter outer cylinder portion and an outer small-diameter outer cylinder portion arranged double-sidedly around the outer periphery of the honeycomb body. In an elliptical metal carrier having a large-diameter outer cylinder part and composed of an outer cylinder body consisting of an arcuate part and a flat part, the flat part of the outer cylinder body is connected to the outer peripheral surface of the small-diameter outer cylinder part and the diameter A thermally expandable member is interposed between the inner circumferential surface of the large outer cylindrical portion and at least a part of the area excluding both ends in the axial direction, and the flat portion of the large diameter outer cylindrical portion is A metal carrier characterized in that the curvature of the portion covering the thermally expandable member is greater than the curvature of the flat portion of the small diameter outer cylinder portion to increase rigidity.
