<P>PROBLEM TO BE SOLVED: To provide a catalyst device which is stored in a cylindrical container in the state of winding a mat on a catalyst support, having simple construction for fixing the mat and the catalyst support into the container without giving trouble to its manufacturing processes. <P>SOLUTION: The catalyst device 1 includes the ceramics catalyst support 10 internally supporting a catalyst which purifies exhaust gas from an internal combustion engine, an outer cylinder 13 storing the catalyst support 10, and the holding mat 12 provided between the outer cylinder 13 and the catalyst support 10. On at least part of the inner surface of the outer cylinder 13, a material is arranged which is easier to oxidize than a stainless material in the exhaust gas from the internal combustion engine. <P>COPYRIGHT: (C)2010,JPO&INPIT |
