Claims

[Scope of Claim for Utility Model Registration] A metal carrier for an exhaust gas purification catalyst comprising a honeycomb body formed by stacking a flat plate and a corrugated plate and winding them into a roll shape, and an outer cylinder housing the honeycomb body, comprising: The outermost periphery of the body is formed by a flat plate, and a convex portion is provided at the outermost periphery of the flat plate, the convex tip of which abuts against the inner peripheral surface of the outer cylinder to form a gap with the outer cylinder, A metal carrier for an exhaust gas purification catalyst, characterized in that a forming stress relieving portion is provided at a boundary portion between the convex portion and the flat plate in the longitudinal direction of the flat plate.
