この考案は前車体と後車体とからなる三輪車に
関し、特にその後車体を覆うカバーに係るもので
ある。[Detailed Description of the Invention] This invention relates to a tricycle consisting of a front body and a rear body, and particularly relates to a cover that covers the rear body.
前１輪を有する前車体と、後２輪を有しこの後
輪間に駆動ユニツトを備えた後車体とを左右揺動
自在に連結し、前記後車体が合成樹脂製のカバー
で覆われた三輪車がある。この種の従来の三輪車
においては、後車体の前記カバー全体が合成樹脂
により形成されていた。合成樹脂によるカバーは
成形性がよく軽量であるという特長を有するが、
熱に対して変形を生じ易く、このため、従来の三
輪車ではこのカバーと排気マフラとの間隙を充分
大きくとつていた。 A front vehicle body having one front wheel and a rear vehicle body having two rear wheels and a drive unit between the rear wheels are connected so as to be swingable left and right, and the rear vehicle body is covered with a synthetic resin cover. There is a tricycle. In this type of conventional tricycle, the entire cover of the rear vehicle body is made of synthetic resin. Covers made of synthetic resin have the advantage of being moldable and lightweight;
It is easily deformed by heat, and for this reason, in conventional tricycles, the gap between this cover and the exhaust muffler has been made sufficiently large.
一方、排気マフラの容量を大とすることはエン
ジン性能向上のために有効であるが、前述の如く
排気マフラの容量を大とすればカバーとの間隙が
狭くなり好ましくない。また、排気マフラが大と
なつた分だけカバーを離すとすれば、後車体が大
きくなり外観性その他の面で不都合となる。 On the other hand, increasing the capacity of the exhaust muffler is effective for improving engine performance, but as described above, increasing the capacity of the exhaust muffler is undesirable because it narrows the gap with the cover. Furthermore, if the cover is separated by the size of the exhaust muffler, the rear body of the vehicle will become larger, which will be inconvenient in terms of appearance and other aspects.
この考案は上記事情に鑑みてなされたもので、
後車体のカバーの耐熱性を効果的に高めて、後車
体を大きくすることなく排気マフラの容量アツプ
を可能とする三輪車を得ることを目的とするもの
である。 This idea was made in view of the above circumstances,
To provide a tricycle which can increase the capacity of an exhaust muffler without increasing the size of the rear body by effectively increasing the heat resistance of the cover of the rear body.
以下本考案の一実施例を図面に基づいて説明す

ａをあけている。 The cover 8 of the rear vehicle body 5 covers the drive unit 4,
Exhaust muffler 15, carburetor 12, air cleaner 1
3. It has a shape that covers the left and right rear wheels 3, etc. This cover 8 is made of synthetic resin as mentioned above, but the upper part of the exhaust muffler 15 (including the upper part of the air cleaner 13 etc. in this embodiment) is cut out and a perforated metal plate 16 is attached to this part. There is. This metal plate 16 has a cut-out hole 16a in the upper part of the exhaust muffler 15. Further, this metal plate 16 is bent at the rear end to form a bent portion 16.
b is attached to the cover 8 by inserting it into the back side of the cover 8 and fixing the front end portion to the cover 8 with a bolt 17 with a knob. In addition, this cover 8
There are cut holes 8 on the left and right sides for air intake.

The air flowing into the engine flows as shown by the arrow in FIG. 4, and one flow cools the engine 9 and the exhaust muffler 15.
The other flow is adapted to supply air to the air cleaner 13. The lower end of this shielding plate 18 is fixed to the transmission case 10 with bolts 19 as shown in FIG. 6, and the upper end is bent to form a receiving part 18a as shown in FIG. Edge piece 8
I support b. Note that the left and right ends 1 of the metal plate 16
6c is in contact with the edge piece 8b of the cover 8 via the rubber 20, and is supported by the receiving portion 18a of the shielding plate 18. Note that the upper end of the central shielding plate 18 supports the muffler 15.

る。 In the rear vehicle cover 8 constructed as described above, since the upper part of the exhaust muffler 15 is made of a metal plate, the heat of the exhaust muffler 15 does not affect the metal plate 1.
6 does not cause thermal deformation, and therefore the gap between the exhaust muffler 15 and the metal plate 16 can be narrowed. Therefore, even if the height of the cross section of the exhaust muffler 16 is increased to increase the capacity, the cover 8
There is no need to separate the exhaust muffler 16 from the exhaust muffler 16. Further, since the metal plate 16 has a simple shape and the other parts are made of synthetic resin, the cover as a whole has improved heat resistance without impairing moldability.

となつた。 As explained above, the present invention connects a front vehicle body having one front wheel and a rear vehicle body having two rear wheels and having a drive unit between the rear wheels so as to be able to swing from side to side. In a tricycle covered with a synthetic resin cover, an exhaust muffler is disposed above the drive unit, and the upper part of the muffler of the cover is made of a perforated metal plate, so that the gap between the cover and the exhaust muffler is reduced. This makes it possible to increase the capacity of the exhaust muffler without increasing the size of the rear body, or by bringing the exhaust muffler closer to the cover, the limited space inside the cover can be saved. It became possible to use it effectively.
