Claims

[Scope of utility model registration request]

A cylindrical ceramic catalyst carrier is arranged between two semicircular half members, the half members are fixed to each other, and a corrugated outer periphery buffer member is covered on the outer periphery of the ceramic catalyst carrier. In the catalytic converter that is fitted, a wavy engagement portion having a shape corresponding to the waveform of the outer periphery buffer member is provided on a part or all of the inner surface of the half member facing the outer periphery buffer member. Features a catalytic converter.
