During this sound absorption process, the outer cylinder and the partition plate are exposed to high-temperature exhaust gas, but because the exhaust gas hits differently, a temperature difference, and therefore a thermal expansion difference, occurs between the two, and as a result, the partition plate is radiused. It extends outward in the direction and is relatively displaced so as to approach the outer cylinder. Here, a partition plate having an outer dimension smaller than the inner dimension of the outer cylinder (at least by the amount of deformation due to thermal expansion) has a collar portion formed on the entire outer circumference between a pair of mounting plates fixed to the inner surface of the outer cylinder. It is sandwiched without a gap, and a part of this flange is brought into contact with the inner surface of the outer cylinder, and the flange and the mounting plate are fixed by, for example, welding in the circumferential partial area including this contact portion. ing. Therefore, even if the partition plate is extended outward in the radial direction with the fixed point by the welding or the like as a fixed point, this extension is absorbed by the radial gap in the mounting plate and does not press the outer cylinder, On the other hand, the axial expansion due to the difference in thermal expansion of the collar portion of the partition plate with respect to the outer cylinder is constrained by the mounting plates on both sides and presses this mounting plate outward. Therefore, since the outer cylinder is not pushed outward by the partition plate in the radial direction and a large stress is not applied, the outer cylinder is not cracked or damaged, and the partition plate is in close contact with the mounting plate in the axial direction. Since it is firmly fixed by, it does not vibrate alone due to the vibration of the engine or the like.

の取付板６,６を外側へ押圧する。The exhaust gas silencer having the above structure operates as follows. Exhaust gas inlet pipe 23 at one end of the exhaust gas silencer
The exhaust gas flowing into the outer cylinder 21 from the outer cylinder 21 passes through the communication pipes 3 of the partition plate 1 and sequentially passes through each chamber partitioned by the partition plate 1 to absorb noise, and exhaust gas from the other end of the outer cylinder 21 is exhausted. It is discharged from the gas outlet pipe 24 to the outside. In this sound absorption process, the outer cylinder 21
And the partition plate 1 is exposed to high-temperature exhaust gas, but since the exhaust gas hits differently, a temperature difference and therefore a thermal expansion difference occurs between them, and as a result, the partition plate 1 is indicated by the arrow in FIG. As shown in the figure, the welding fixing point on the approximately 1/4 circle is used as a fixed point to extend radially outward and relatively displace so as to approach the inner circumference of the outer cylinder 21. Here, the partition plate 1 has an outer diameter that is smaller than the inner diameter of the outer cylinder 21 by at least the amount of deformation due to thermal expansion, and the outer periphery of the partition plate 1 other than the welding fixing points P 1 to P 2 and the outer cylinder 21. While there is a gap G shown in FIG. 3 between the periphery and the periphery, the collar portion 2 on the outer periphery of the partition plate 1 has no gap between the pair of mounting plates 6 in the axial direction as shown in FIG. It is caught in. Therefore, even if the partition plate 1 extends outward in the radial direction as shown by the arrow in FIG. 3, this extension is absorbed by the gap G,
The outer cylinder 21 is not pressed, and on the other hand, the expansion in the axial direction due to the difference in thermal expansion of the collar portion 2 of the partition plate 1 with respect to the outer cylinder 21 is:
As shown in FIG. 2, the mounting plates 6, 6 abutting on both sides are constrained to push the mounting plates 6, 6 outward.

ることができる。Therefore, since the outer cylinder 21 is not radially expanded outward by the partition plate 1 and a large stress is not applied, the outer cylinder 21 is not cracked or damaged due to the stress applied to the outer cylinder 21, and the partition plate 1 is also prevented. Is closely attached to the mounting plates 6 and 6 and is firmly fixed in the axial direction, so that it does not vibrate alone due to vibration of the engine or the like. Further, since the collar portion 2 formed on the entire circumference of the partition plate 1 is in axial contact with the mounting plates 6, 6 protruding on the entire inner circumference of the outer cylinder 1, the exhaust gas does not pass through the communication pipe 3. The sound deadening effect can be improved without leaking to the next room.

までもない。In the above embodiment, since the sound absorbing material 4 is provided on the entire surface of the partition plate 1 on the side of the collar portion 2, the sound deadening effect can be further improved. In the above embodiment, the collar portion 2 has a U-shaped cross section, and approximately 1/4 of the entire circumference is in contact with the inner surface of the outer cylinder. However, the cross-sectional shape of the flange portion and the contact length with the outer cylinder. It is not limited to this. Further, it goes without saying that the present invention can be applied to a silencer of a type other than the round exhaust gas silencer of the embodiment.

The partition plate that has a through hole through which the through hole is made has an outer dimension that is smaller than the inner dimension of the outer cylinder by at least the amount of deformation due to thermal expansion, and the flange portion formed on the entire outer circumference is sandwiched between the pair of mounting plates without a gap. , The collar portion is partially brought into contact with the inner surface of the outer cylinder, and the collar portion and the mounting plate are fixed in a partial area in the circumferential direction including the contact portion, so that the partition plate is separated by the difference in thermal expansion. Even if it extends radially outward and approaches the outer cylinder, the partition plate does not press the outer cylinder radially outward, the outer cylinder receives a large stress and does not crack or break, and the partition plate is Since it closely adheres to the mounting plate and is firmly fixed in the axial direction,
It does not resonate due to engine vibration.
