Abstract
An exhaust pipe 1 having a circular cross section is connected to a circular cylindrical housing 2 which creates part of pipe conduit. The housing 2 forms a storage space 21 having a diameter larger than the diameter of the exhaust pipe 1 and connecting to the rear connection part 22. The connection part 22 is tapered toward the downstream exhaust pipe 12 and the diameter of the connection part 22 is gradually reduced and its opening is welded into the opening of the downstream exhaust pipe 12. And a cylindrical honeycomb catalyst carrier 3 is stored in the storage space 21 so that the outer surface of the catalyst carrier is in contact with the inner surface of the storage space 21. An expanded portion 23 having a diameter larger than the diameter of the storage space 21 is outwardly expanded from the outer circumference of the housing 2 and connectingly provided on the front face of the storage space 21. The diameter of the expanded portion 23 is gradually reduced toward the upstream exhaust pipe 11 and welded into the opening of the outer wall of the exhaust pipe 11.
