Abstract: The present disclosure provides a muffler with a simple structure and a low cost. The muffler is formed by an exhaust pipe. The exhaust pipe has an extension direction and a radial direction, an exhaust gas is discharged through the exhaust pipe. At least a partial region of an interior of the exhaust pipe is divided into a muffling chamber and an exhaust passage portion by a partition plate arranged along the extension direction. A cross-sectional area of the exhaust passage portion is larger than that of the muffling chamber. At a downstream end portion of the muffling chamber in a flow direction of the exhaust gas, a peripheral wall of the exhaust pipe on the muffler chamber side is engaged with the partition plate, thereby closing a downstream opening of the muffling chamber in the flow direction of the exhaust gas.
