ARRANGEMENT FOR FITTING AN EXHAUST CLEANING UNIT IN AN EXHAUST PASSAGE

摘要

An arrangement for fitting an exhaust cleaning unit (2) in an exhaust passage (1b): An annular resilient component (7) is fitted around the exhaust cleaning unit (2) at a distance from a gasket (5). The annular resilient component (7) has a first contact portion (7a) which comes into contact with a wall surface (3) of the exhaust cleaning unit (2) and a second contact portion (7b) which comes into contact with a wall surface (1b) of the exhaust passage when the exhaust cleaning unit (2) is in a fitted state in the exhaust passage. The annular resilient component (7) keeps the exhaust cleaning unit (2) in a centered position in the exhaust passage with a spring force.
