Abstract
An exhaust muffler structure of an internal combustion engine in which a catalyzer is readily and easily mounted and removed to carry out the assembling work of the muffler and the maintenance work such as cleaning and replacing the parts of the muffler with ease; the generation of vibration and noise are to be prevented; and the purification capacity and durability of the catalyzer are to be improved. The exhaust muffler structure comprising: an exhaust muffler having inner and outer exhaust muffler halves which are detachably combined with each other; a communication hole formed on the exhaust muffler for guiding exhaust gas from an internal combustion engine to the exhaust muffler; a cylindrical member having a catalyzer between resilient supporting nets, characterized in that the cylindrical member is disposed in a space in the exhaust muffler with a body of the cylindrical member being supported between the both inner and outer exhaust muffler halves.
