（なる。Conventionally, in a muffler for an exhaust system of an internal combustion engine, the outer box forming the chamber is made of a steel plate because the exhaust gas is at room temperature. Furthermore, in order to enhance the sound deadening effect and to provide insulation, molded glass wool ki, which is formed by compressing cotton-like glass wool, is adhered to the inner surface of the outer box. This kind of silencer has a double structure because the outer box is made of steel plate, which increases the number of seedlings, and the molded glass cool wall is attached to the same part of the outer box. It is complicated and costly.

る。In this embodiment, the outer box 2 is divided into two parts as shown in FIG. That is, the outer box 2 consists of two outer box pieces 3 and 4 that are open on one side, and hook parts 3a and 4a that engage with each other (the other side) are formed at the joints of both outer box pieces 3 and 4. A heat-resistant liquid adhesive is applied to the hook parts 3a and 4a, and the two parts 3a and 4a are interlocked and joined together, and then the joint is reinforced by securing them with the U-shaped clasp 5 of a stapler. The muffler A and the exhaust pipe 1 are joined by inserting the exhaust pipe 1 into a steel grommet 6 provided in the outer case 2 and brazing the insertion portion.

The third chamber 9C is divided into three fits. These partition walls 10.11 have cylindrical parts IQa, l on their periphery.
la is fixed to the outer box 2 by fitting into an annular groove 2a provided on the inner surface of the outer box 2. Cylindrical part 10a as needed,
It is advisable to apply a heat-resistant adhesive to join the parts.

A communication pipe 13 that communicates with the second chamber 9b and a differential user pipe 1.4 that communicates the second chamber 9b directly with the outside are provided. This Defuyu - The Pipe 1
4 has a large number of small holes 14a, and a cotton-like ? It is filled with lath wool, and the end is brazed to a steel grommet 17 provided on the outer box 2.

作用番こより一層蔦い消音効果が得られる。As described above (in the combined silencer A), the exhaust gas from the engine enters the first chamber 9a through the exhaust pipe 17!l-, the former fuser pipe section 1b at the end, and passes through the continuous pipe 12 to the first chamber 9a. and enter the third chamber 9C.
It passes through the communication pipe 13 into the second chamber 9b and is discharged to the outside from the differential user pipe 14, during which time compression and expansion are repeated to produce a silencing effect. In this case, chamber 9
is made of molded glass wool. Because of its sound absorbing effect, it can achieve even greater sound deadening effects.

また、エンジンからの排気は高温であるが、グラスウー
ルの断熱性がきわめて高いので、外箱２の外表面の温度
を充分低く抑えることができる。Furthermore, although the exhaust gas from the engine is at a high temperature, the temperature of the outer surface of the outer box 2 can be kept sufficiently low because the glass wool has extremely high heat insulating properties.

を持つ＠そして、鋼板を用いていないので軽量である。As mentioned above, the outer box 2 of the present invention uses only molded glass wool and does not use a steel plate. However, when molded glass wool is impregnated with a predetermined resin and hardened, it has a tensile strength higher than that of ordinary fiber reinforced plastic (FRP). It has sufficient strength to meet the requirements for the outer box of a silencer, and is lightweight because it does not use steel plates.

It is not complicated and can be manufactured at low cost.The four-layer impregnated surface also has the effect of repelling water, oil, etc.
