Abstract of the Disclosure The known muffler of an industrial engine, in which a channel communicating with an exhaust gas outlet is integrally formed on the inside of a muffler main body made of an aluminium diecast, and an inner lid is mounted to the open side of the channel to form an exhaust gas passageway serving also as a tail pipe, within the muffler main body as disclosed in Japanese Utility Model Applica- tion No. 63-127369 (1988) is improved. The improvements reside in that a cross-section area of the channel is reduced gradually or in a stepwise manner from its inlet towards the exhaust gas outlet so as to prevent carbon from adhering to the exhaust passageway, and in that at the exhaust gas outlet is formed a projecting wall adapted to butt against the inner lid, integrally with the muffler main body so as to prevent the exhaust gas escape without passing through the exhaust gas passageway.
