金）101をＵ溝に合わせ排気通路130を形成する。As shown in FIG. 1, the U-shaped groove 103 is integrally formed with the die casting body 100.
The wall 100c is provided so as to communicate with the muffler outlet 100b so as to form an exhaust passage 130 by further fitting a lid (sheet metal shown in the figure) 101 made of die-cast or sheet metal to the U groove.
本体と一体に形成された壁100ｃと、蓋101とにより簡単
に通路が形成され、消音器出口100ｂにつながりテール
パイプとしての機能をもつ。A passage is easily formed by the wall 100c integrally formed with the main body and the lid 101, and the passage is connected to the muffler outlet 100b and has a function as a tail pipe.
第１図は消音器本体100と消音器出口周辺を示す正面図
である。アルミダイカスト製の本体100より一体形成さ

02で本体100に固定して、排気通路130を形成する。FIG. 1 is a front view showing the muffler body 100 and the vicinity of the muffler outlet. A U-shaped groove 103 of a U-shaped path formed by a wall 100c integrally formed from a body 100 made of aluminum die casting
Then, attach the lid 101 made of aluminum die casting or sheet metal to the screw 1
It is fixed to the main body 100 at 02 to form the exhaust passage 130.
第２図は第１図のＡ−Ａ断面で、排気通路130の一部を
示しており、消音器出口100ｂに連通すべく傾斜した排
気通路部130ａを設ける。FIG. 2 is a sectional view taken along the line AA of FIG. 1, showing a part of the exhaust passage 130, and an inclined exhaust passage portion 130a is provided to communicate with the muffler outlet 100b.
第３図は第１図のＢ−Ｂ断面で、消音器蓋３と本体100
