The purpose is to provide a product with a small number of parts, easy to manufacture, and parts that can be used for general purposes, making it possible to provide the product at a low price. Silencers having various structures are known. In this silencer, openings at both front and rear ends of a cylindrical body 10 are connected to end plates 2, respectively.
．． The inside of the casing 4, which is closed by a casing 4, is surrounded by three partition walls 5.6.
7 is divided into four chambers 8, 9, and 10, IIK, first to fourth, in order from the front side (left side in the drawing).

The rear end of the third chamber 10 is opened by passing through the two partition walls 5.6 in an airtight manner. In addition, the outlet pipe] 3, which is inserted into the casing 4 by passing through the rear end plate 3 airtightly, crosses the three rear chambers 9, 'l0-11, and the three partition walls 5.6. .7
The front end is opened to the -th chamber 8 which is the closest to the front by airtightly passing through the chamber. Further, both ends of the communication pipe 140 passing through the two front partition walls 5.6 open into the first chamber 8 and the third chamber 10, respectively. In addition, appropriate small holes (not shown) are bored in the portion of the six pipes 12, 13, and 14 located in the second chamber 9 and in the portion of the outlet pipe 13 located in the fourth chamber JJ.

ことが多い。When using the silencer configured as described above to attenuate exhaust noise, the exhaust gas is sent in through the inlet pipe 12 and discharged through the outlet pipe 13, during which time the flow path expands and contracts repeatedly, causing internal damage. The second concave chamber 9.1 reduces the energy
1, the noise is attenuated and pulsated or smoothed by the resonance effect of 0. A muffler constructed and operated as described above has conventionally had a partition wall 5 inside a cylindrical body 1, as shown in FIG. .6.7 fixed by welding and 6 pipes 1 passing through each bulkhead 5.6.7
The contact portion between 2.13.14 and this bulkhead 5.6.7 is welded, and end plates 2.3 are welded to the openings at both ends of the body 10, and the edges of both ends of this body 10 and the peripheral edge of each end plate 2.30 are welded. The parts of the inlet pipe 12 passing through the end plate 20 and the part of the outlet pipe 13 passing through the end plate 30 are respectively welded. Although not shown, the fuselage 1 includes a casing 4
The body 1 vibrates due to internal noise, and in order to prevent radiated noise from propagating around the muffler, a double structure is often used.

部品が少なく消音器の種類ごとに多種の部品を用意する
必要があり、−上述の組立作業が面倒なことと併せて製
品の値段を高くする原因となっていた。However, in the conventional silencer assembled as described above, the bulkhead or tube is fixed at a predetermined position in the body 1, or the end plates are wrapped and fixed around the openings at both ends of the body 10. The work was troublesome. In addition, the structure and size of the silencer must vary depending on the displacement of the internal combustion engine, etc.
In the conventional silencer shown in Figure 1, there are few parts that can be used for general purposes, and it is necessary to prepare a variety of parts for each type of silencer. This caused the price to rise.

なく、部品数の低減化も図れる。The function of the silencer of the present invention constructed and assembled as described above is the same as that of the conventional silencer shown in FIG. 1, so a description of the function will be omitted. Since the silencer can be constructed and assembled in different ways, it is easy to assemble each part, and many of the parts can be reused even when manufacturing different types of silencers, and many types of manufacturing equipment can be prepared to manufacture many types of parts. becomes unnecessary. That is, if the heights of the standing walls of each element are made different, it is possible to create many different types of silencers simply by changing the way they are combined, and even more types of silencers can be obtained by changing the number of combinations. Furthermore, since the joint portion of the casing 4 formed by joining each element has a double structure and functions as a reinforcing frame for the peripheral wall of the casing, there is no need to make the peripheral wall of the casing 40 a double structure. The number can also be reduced.
以上に述べた様に、本発明の消音器は組立作業の容易化
