A muffler connected to an exhaust system of an automotive or like internal combustion engine for damping noise, which accompanies engine exhaust, using a sound absorbing member. An intertwined meshwork in a tubular configuration serves as means for covering and firmly retaining the sound absorbing member, which is wound around a perforated pipe, on the outer periphery of the perforated pipe. The tubular meshwork is produced by intertwining in a desired density strings each of which is made up of a number of strands.
