Claims

[Scope of utility model registration request]

In a metal catalytic converter, a metal corrugated plate and a flat plate are stacked, these are wound multiple times to form a core part, this core part is housed in a container, and exhaust gas is passed through the core part. , an end face of the exhaust gas inflow side of the core portion is protruded toward the exhaust gas inflow side to form a conical protrusion, and an end face of the exhaust gas outflow side of the core portion is recessed toward the exhaust gas outflow side. A metal catalyst characterized in that a cone-shaped recess is formed, and a movement prevention member having a large number of exhaust gas flow holes and abutting on the exhaust gas outflow side end face of the core portion is arranged in the container. converter.
