Claims

[Scope of utility model registration request]

An exhaust inlet 16 is opened in the rear wall 15 of the muffler 12 of the engine 1, and a plurality of bolt insertion tubes 20 are respectively positioned around the exhaust inlet 16.
A muffler mounting seat 19 and a plurality of screw holes 22 are formed around the outlet 18 of the exhaust port 5 of the engine body 8, and a muffler mounting seat 19 is provided vertically across the rear wall 15 and the front wall 21. By inserting a plurality of bolts 13 from the front into each bolt insertion tube 20 and screwing them into each screw hole 22 with the rear wall 15 of 12 in contact with each other, the muffler 12 is attached to the engine body 8 with the bolts 13. In the engine muffler mounting device configured to be fixed to the rear wall 15 of the muffler 12,
Of these, the rear wall portion 15a surrounding the exhaust inlet 16 is expanded rearward to form a curved annular seat 17, and the curved annular seat 17 passes through a portion closer to the exhaust inlet 16 than the bolt insertion tube 20. An engine muffler mounting device characterized in that a curved annular seat 17 is brought into contact with a muffler mounting seat 19 either directly or via a gasket 31.
