ABSTRACT:
An exhaust purifying device applicable to an exhaust system extending from an internal combustion engine has a casing and a core received in the casing. The core has a honeycomb structure implemented by a corrugated sheet metal and a flat sheet metal rolled up together in a spiral configuration. Part of the flat sheet forming the outer periphery of the core is formed with a plurality of openings. The core is locally affixed to the casing by a solder applied to the portions of the flat sheet surrounding the openings and opposite edges of the flat sheet. This is successful in surely and stably affixing the core to the casing despite that the solder is implemented as an inexpensive powdery solder.
