対象個所は、前記の他にキャブレータ１１．エアクリー
ナ１３等を適当に選択するものである。Regarding the above, the present invention targets the cooling air inlet 4 and the muffler 8, and extends a flat cross-shaped dust cover 15 through the tank flange 6a of the fuel tank 6 as shown in the second figure. As shown in the third figure, the cross section of the cover 15 is in the shape of an arc extending from the tank flange 6a to the circumferential side and the lower side, and the dust-proof areas covered by the cover 15 include, in addition to the above, the carburetor. 11. The air cleaner 13 and the like are appropriately selected.
なお、エアクリーナ１３に関しては第４図示の如き上方
派出方式に依る場合は、単独にカバーリングを構成する
ことがある。In addition, regarding the air cleaner 13, if the air cleaner 13 uses an upward delivery method as shown in the fourth figure, it may constitute a covering ring alone.
又、第５図、第６図は前記例に従う好適な変形例を示し

シーム溶接にても具体化できる。Further, FIGS. 5 and 6 show a preferred modification according to the above example, in which 15a is a cover rib disposed to cross the dustproof cover 15 and protrudes upward, and has the purpose of being lightweight and increasing rigidity. Further, 16 is a fastening device that fixes the tank stay 14 and the fuel tank 6 via a vibration-proof rubber 17 with the dust-proof cover 15 also in a collinear state. Although it is provided to fix the dustproof cover 15, it can also be realized by well-known seam welding.
更に防塵カバー１５は自らを防音用ロックウール（岩石

る。Therefore, when the air-cooled engine E is mounted on a combine harvester or the like as described above, the dustproof cover 15 prevents the straw shoulders from reaching the cooling air inlet 4 or the muffler 8, etc., and as a result, the cylinder 2 around or muffler 8
Since straw waste is not accumulated in the vicinity, the cooling performance is maintained at a predetermined level, and the risk of fire with respect to the muffler 8 is prevented.
更に同防塵カバー１５はエンジンＥ側での騒音と上昇す
