ABSTRACT:
An engine is disposed in a top cowling. Burned gas produced in the engine is discharged to the outside through a first exhaust pipe, a second exhaust pipe, a third exhaust pipe, exhaust passage, and a exhaust passage. A catalyst is disposed to be housed in the first exhaust pipe and the second exhaust pipe. The first exhaust pipe and the second exhaust pipe are disposed in the top cowling. A fan is provided above the catalyst. As a result of this unique structure, a temperature increase in the cowling is prevented from being caused by heat radiated from the catalyst.
