騒音化も図れる。As described above, according to the present invention, the bonnet 5 covers the engine 2 and the top and side portions of the starting device 3 and the muffler 4, and the inside of the hood 5 is provided with the partition walls 61 and 62 for the starting device chamber. 30, engine room 20, muffler room 40
The three chambers are defined, and these three chambers are at a low temperature from the starting side equipment chamber 30 to the engine 2 and the engine chamber 20,
At high temperature, it was ducted toward the muffler chamber 40 on the exhaust side, and because the cooling air was forcedly passed through the passage, there was little backflow or retention of air, and the heat balance inside the bonnet 5 was kept good, Not only the engine 2 part,
The starting device 3 and the muffler 4 can be cooled well, and since the bonnet 5 covers the high temperature and vibrating parts around the engine, safety and dustproof / waterproof property can be improved, and the engine sound and exhaust sound are leaked to the outside To reduce noise.
