Abstract
A muffler for an internal combustion engine includes an outer box composed of a plurality of separate bodies made of a formed sound insulation material and having portions joined by an adhesive, the outer box having an inlet for introducing an exhaust gas from the internal combustion engine and an outlet for discharging the exhaust gas, and a reinforcing member mounted on the joined portions to seal and reinforce the same. The muffler is simple in construction, has a good sound insulation capability, is lightweight, and sufficiently mechanically strong.
