Abstract
The expansion chamber shell into which the gas from a noise source, such as an internal combustion engine, is rushed is held in an outer shell in a manner to define therebetween a clearance which acts as a sound damping means against the gas passing through the muffler. Thus, the noise caused by the inevitable vibration of the expansion chamber shell is prevented from being directly transmitted to the outside of the muffler.
