PROBLEM TO BE SOLVED: To prevent heat from being accumulated within an engine chamber after an engine is stopped. SOLUTION: The engine chamber 11 is formed of an engine surrounding body 10, and an opening 29 is formed in a top surface plate 24 of the body 10 and covered with a lid 30. The lid 30 is formed with an exhaust part 34, provided with an outside cover 40 so as to cover the exhaust part 34, and formed with a lateral exhaust port 41. Consequently, the heat within the engine chamber 11 is discharged from the exhaust port 41 through the opening 29 and the exhaust part 34 after the engine 4 is stopped, in order to prevent the heat from being accumulated within the engine chamber 11.
