Claims

[Claims for Utility Model Registration] (1) A corrugated metal plate and a flat plate are overlapped, and these are wound multiple times to form a core part, and this core part is housed in a cylindrical container, and Annular members fixed to the cylindrical container are fitted onto both ends of the outer periphery of the core portion, and movement of these annular members restricts movement of the core portion in the axial direction within the cylindrical container. In a metal catalytic converter in which a blocking portion is provided protruding toward the center, the movement blocking portion is disposed at a predetermined distance from an end face of the core portion, and the movement blocking portion is provided with an outer peripheral portion of the core portion. A metal catalytic converter characterized by forming a notch through which exhaust gas flows. (2) Layer a metal corrugated plate and a flat plate, wind them multiple times to form a core part, house this core part in a cylindrical container, and both ends of the outer periphery of the core part An annular member fixed to the cylindrical container is fitted onto the annular member, and a movement preventing portion for restricting movement of the core portion in the axial direction within the cylindrical container is attached to the annular member toward the center. In the protruding metal catalytic converter, the movement blocking portion is formed at a predetermined angle in a direction opposite to the end surface of the core portion,
A metal catalytic converter, characterized in that exhaust gas is allowed to flow through the outer circumferential portion of the core portion.
