Abstract

PURPOSE:To improve the noise silencing effect of a muffler by installing a cylindrical noise absorbing material in a position where exhaust gas flows in the axial direction on both inner and outer circumferential sides of the said material. CONSTITUTION:The inside of an exhaust muffler 10 is partitioned off by partition walls 12-15, and respective silencer chambers S1-S4 are formed there. A cylindrical noise absorbing material 16 held by punching metals 17, 18 is installed and kept in each inner circumferential part of the partition walls 12, 13. Exhaust entered in the muffler 10 flows parallelly on both inner and outer circumferential sides of the noise absorbing material 16 as in arrows (a), (b) and then it flows into the second silencer chamber S2. With this constitution, since exhaust energy is absorbed by both these inner and outer circumferential sides of the absorbing material, a noise silencing effect is improvable.
