Abstract
An exhaust muffler of this invention is constituted of a muffler main body having an opening, a muffler cover closing this opening of said muffler main body and being capable of attachment and removal, a partition separating said muffler main body and said muffler cover, and a long exhaust extension pass formed by combination of said partition and said muffler cover and extending by meandering in said muffler cover. On said partition, a communicating hole is provided to communicate between said muffler main body side and said muffler cover side. A catalyst is provided on the surface of said partition facing said muffler main body to purify exhaust gas. Thus, exhaust gas introduced into said muffler main body flows into the space formed by said muffler cover through said communicating hole after purified by said catalyst. This exhaust gas passes meandering through said exhaust extension pass during which exhaust gas is sufficiently cooled down and then discharged into atmosphere.
