CATALYST APPARATUS, METHOD FOR PRODUCTION OF CATALYST APPARATUS, AND STRUCTURE RETAINING CATALYST CARRIER

摘要

In a catalyst device that contains a catalyst carrier in an outer cylinder, the catalyst carrier is fixed to the outer cylinder with a simple structure. A catalyst device 1 is provided with a catalyst carrier 10 that carries a catalyst having an exhaust purification function, an outer cylinder 13 that contains the catalyst carrier 10, and a holding mat 12 disposed between the catalyst carrier 10 and the outer cylinder 13, in which a high friction portion 14 is disposed between the catalyst carrier 10 and the outer cylinder 13 so as to prevent movement of the holding mat 12.
