Claims

[Scope of utility model registration request]

A large number of conductive holes are provided that communicate from one end surface of the cylindrical body to the other end surface opposite to this end surface, and a clamping member is disposed on the one end surface side and the other end surface side, and the clamping member is disposed on the one end surface side and the other end surface side. In the catalytic converter in which the cylindrical body is held between the cylindrical bodies by pressing and/or abutting against the peripheral edges of the end faces, the peripheral edges are spaced apart from each other on at least one of the one end face and the other end face. A catalytic converter characterized in that the holding member is pressed and/or abutted against the peripheral edge portion at a plurality of portions.
