Abstract:
A muffler is provided to improve workability such as welding to improve productivity and quality, and to enable repairing the muffler by exchanging only the damaged components. A muffler(1) includes a housing(8). The housing has a space(2) having a predetermined size. The space is partitioned into several sub-spaces and has a plurality of through-holes(3). Baffles(5) are installed in the through-holes to fix gas guide pipes(4). The housing includes an introducing pipe(6) to receive exhaust gas from an outlet of an engine and an exhaustion manifold to exhaust the exhaust gas after noise is reduced by the gas guide pipes. The housing includes a separator(9) having at least one baffle and coupled with the housing. Coupling ends of the separator is sealed by a packing. The packing is inserted into a recess formed on a coupling end of the separator and the coupling end of another separator is inserted into the recess so that the coupling end is pressed by the packing to couple the separators with each other in sealed state.
