<p>A muffler (21) of a construction machine is formed by respectively coupling silencers (23,24) to entrance and exit sides of an exhaust-gas purifying device (22) by flanges (25,25). In flange coupling portions, mounting seats are provided integrally with lower semicircumferential portions (31) of the flanges of the silencers in a manner such as to protrude toward outer peripheries of the flanges. By coupling the mounting seats to muffler mount brackets (30,30) attached to a muffler mount, the muffler is mounted on the muffler mount.</p> |
