Gas is discharged from the gas passage pipe through the cylindrical body and sound absorber. The cylindrical body has a disk-like partitioning wall axially dividing the interior space thereof. The gas passage pipe has an outer flange and a plurality of pawls cooperating with the flange so as to clamp the partitioning wall therebetween.
