Claims

[Claims for Utility Model Registration] 1. A muffler main body 4 having an exhaust outlet 7 and an exhaust tail pipe 5 into which exhaust gas discharged from the exhaust outlet 7 flows;
An outside air introduction ejector part 11 is provided between the exhaust inlet 10 and the outside air introduction ejector part 11 so as to be able to cause outside air to be mixed into the exhaust gas as the exhaust gas flows from the exhaust outlet 7 toward the exhaust inlet 10. The muffler device is a muffler device that is connected in series with the exhaust gas inlet 10, in which the exhaust gas flows from the exhaust outlet 7 toward the exhaust inlet 10, separately from the ejector portion 11. , an outside air introduction passage W is provided that allows outside air to be mixed into the exhaust gas, and the ejector part 11 and the A muffler device that is arranged in conjunction with the passage W. 2. A muffler main body 4 having an exhaust outlet 7 and an exhaust tail pipe 5 into which exhaust gas discharged from the exhaust outlet 7 flows are connected to each other by connecting the exhaust outlet 7 and the exhaust tail pipe 5.
An ejector for introducing outside air is provided between the exhaust inlet part 10 of the exhaust gas and the exhaust inlet part 10 so as to be able to cause outside air to be mixed into the exhaust gas as the exhaust gas flows from the exhaust outlet 7 toward the exhaust inlet part 10. The muffler device is a muffler device which is provided with a section 11 and is connected in series, and the muffler main body 4 has a protrusion T projecting inwardly from the muffler main body 4 so as to prevent the exhaust gas discharged from the exhaust outlet 7.
