ＩＯによりマフラ１２の熱が燃料タンク５側に漏れてし
まい、燃料タンク５への断熱効果が少なくなってしまう
。Furthermore, when the heat insulating plate 40 is attached to the muffler 12, the muffler 12 directly heats the insulating plate 40, and if it comes into contact with or comes close to the muffler cover 17, the muffler cover 17 may be deformed by the heat. Insulating plate 40 and muffler cover part 1 to avoid
A gap is formed between 7. However, the above gap P'X
Due to the IO, heat from the muffler 12 leaks to the fuel tank 5 side, reducing the insulation effect on the fuel tank 5.
燃料タンク５の断熱を完全にするためにはタンク５と断
熱プレート４０との間隔Ｗを大きく取ればよいが、そう
した場合タンク容１が大幅にυ１限されてしまうという
不具合が生じる。In order to completely insulate the fuel tank 5, the distance W between the tank 5 and the heat insulating plate 40 may be increased, but in such a case, a problem arises in that the tank capacity 1 is significantly limited by υ1.
上記のような不具合を解消するためには断熱プレート４

い。In order to solve the above problems, heat insulation plate 4
0 should be molded with resin integrally with the muffler cover part 17, but even if the heat insulating plate 40 is molded with resin integrally with the muffler cover part 17 as shown by the imaginary line in FIG. It is impossible to make upward and downward cutting dies (arrow T), and resin molding is practically impossible. Even if it were possible, it would not be possible to easily cover the engine from above.
なお第８図中の矢印は樹脂成形時の各金型の抜き方向を
