Abstract

A tubular jacket's (M) inner surface and an exhaust gas treatment unit's outer surface have a connection by means of an adhesive in a connection area when closed and are between 20 and 90 percent free from separate bedding devices fitted between the tubular jacket's inner surface and the exhaust gas treatment unit's outer surface. An independent claim is also included for a method for producing an exhaust gas purifying device on an internal combustion engine with an exhaust gas treatment unit and a tubular jacket.
