Claims

[Scope of utility model registration request]

In a catalyst device comprising a catalyst case that holds a catalyst body having an oval cross-section and a presser that prevents deformation of the catalyst case due to thermal distortion in the short axis direction of the catalyst body, the presser is configured to absorb exhaust heat. 1. A catalyst device comprising a compensation mechanism for compensating for the amount of expansion and preventing the catalyst case from being deformed when the catalyst case is expanded.
