。 The shell has a double structure of an outer shell and an inner shell, and the openings at both ends of the shell are closed by end plates, and the inside thereof is partitioned by at least one buttful plate, and an exhaust gas conduit passes through the end plate and the buttful plate. In a large muffler, a concave portion is formed along the circumferential direction of the circumferential wall of the exhaust gas conduit, and the buff-full plate is bent to form an exhaust gas conduit whose outer diameter is slightly larger than the outer diameter of the exhaust gas conduit. A through hole is provided, a protrusion that engages with the recess provided in the exhaust gas pipe is provided on the bent piece of the through hole, and an inner A large muffler characterized by being provided with a protrusion that contacts the shell and slides on the inner periphery of the inner shell in conjunction with the expansion of the exhaust gas conduit in the axial direction due to thermal expansion.
