<p>PROBLEM TO BE SOLVED: To secure a silencing effect in a structurally simple manner by controlling an exhaust flow.SOLUTION: A separator 30 partitions the inside of a body cylinder part 26 of a muffler into a first chamber 31 positioned on the upstream side of exhaust air and a second chamber 32 positioned on the downstream side of the exhaust air. A separator forming punching hole 35 is formed in a part, against which the exhaust air does not directly strike along an oriented direction of an opening 21A being a downstream-side end opening of an exhaust pipe 14, of the separator 30.</p> |
