。[Claims for Utility Model Registration] (1) A catalyst carrier is formed by spirally winding a metal plate coated with a catalyst with a gap in between;
In a catalyst structure in which the catalyst carrier is housed in a casing with its winding central axis direction aligned with the flow direction of exhaust gas, the catalyst carrier is divided into two in the central axis direction, and a space is formed between these divided catalyst carriers. In addition to providing
A large number of small holes communicating in the radial direction are formed in a metal plate constituting at least the catalyst carrier on the upstream side of the exhaust flow among these divided catalyst carriers, and a number of small holes communicating in the radial direction are formed between the catalyst carrier and the casing. , A catalyst structure characterized in that a sealing material is disposed to cover the outer periphery of the space. (2) The catalyst structure according to claim 1, wherein a large number of small holes communicating in the radial direction are formed in the metal plate constituting the catalyst carrier on the downstream side of the exhaust flow.
