The muffler is divided into a first expansion chamber and a second expansion chamber across a partition plate. An exhaust hole that allows the expansion chambers to be communicated with each other is formed at the lower part of the partition plate. An exhaust gas is guided from the upstream first expansion chamber toward the downstream second expansion chamber through the exhaust hole.
