Abstract

PURPOSE: To keep a catalyst carrier and a catalyst shell sufficiently and surely sealed up for a long time, by absorbing the scatter in the dimensions of the carrier and the shell.
CONSTITUTION: Two exhaust pipes 2, 3 coupled to an engine are connected to a single exhaust pipe 4 which communicates with muffler. A catalytic converter 5 is installed at the coupled ends of the exhaust pipes 2, 3, 4. The converter 5 has the catalyst shell 7 consisting of half-split parts 71, 72 coupled to each other. The catalyst carrier 6 is provided in the catalyst shell 7. A ceramic cement 25 is coated on the outside surface of the inlet part of the catalyst carrier 6. The rear part 24a of a seal ring 24 is bonded to the ceramic cement 25 on the inlet part of the catalyst carrier 6. The front part 24b of the seal ring 24 is elastically and airtightly fitted on the inside surfaces of the half-split parts 71, 72 of the catalyst shell. The purpose is thus attained.
