該仕切板３の螺旋ピッチ２間に嵌合するように平板２ａ
を螺旋状に巻付けて。First, the spiral partition plate 3 is fixed to the outer periphery of the inner cylinder 1 by welding 4b. Next, the flat plate 2a is fitted onto the outer edge side 3a of the spiral partition plate 3 so as to fit between the helical pitches 2 of the partition plate 3.
Wrap it in a spiral.
仕切板３の外縁側部３ａと螺旋状の平板２ａの両端縁と
を溶接４ａによって固着して外筒２を形成する。The outer cylinder 2 is formed by fixing the outer edge side 3a of the partition plate 3 and both end edges of the spiral flat plate 2a by welding 4a.

部材の邪魔となシ、また美観上も好ましくない。更に、
溶接部４ａが仕切板８の両側にあるため溶接工数が増え
る等の欠点があった。When fitting the flat plate 2a forming the outer cylinder 2 to the outer edge side 3a of the spiral partition plate 3, it is difficult to align the fitting position of the flat plate 2a. The roundness and verticality of the formed outer cylinder 2 are not maintained, resulting in poor finishing accuracy. Further, since the flat plate 2a and the outer edge side 3a of the partition plate 8 are welded 4al, the welded portion 4
The outer edge of the partition plate 3 protrudes from the outer circumferential surface of the outer tube 2 along with a. For this reason, the protrusion gets in the way of the member wrapped around its outer periphery, and is also not aesthetically pleasing. Furthermore,
Since the welded portions 4a are located on both sides of the partition plate 8, there are drawbacks such as an increase in the number of welding steps.
本発明は上記に鑑みなされたもので、外筒と仕切板との

、消音器の製作工数を低減し、仕上り精度及び美観を向
上せしめることを目的とする。The present invention has been made in view of the above, and by joining the outer cylinder and the partition plate on the end face of the outer periphery of the partition plate, the number of man-hours required for manufacturing the silencer is reduced, and finishing accuracy and aesthetics are improved. The purpose is to encourage.
以下、第２図及び第８図を参照して本発明のｌ実施例に
つき説明すると、ｌは内筒、２は外筒、３は仕切板であ

平板２Ａの両端縁とを溶接４Ｃによって固着して外筒２
を形成する。A spiral partition plate 3 is fixed to the outer periphery of the inner cylinder 1 by welding 4b. Next, two flat plates cut to a width approximately equal to the helical pitch P of the partition plate 3 are placed on the outer circumferential edge *8A of the partition plate 8 so that the inner peripheries of both ends thereof are in contact with the outer circumferential end surface aAi of the partition plate 8 to form a spiral shape. The outer peripheral end surface 3A of the partition plate 8 and both edges of the flat plate 2A are fixed by welding 4C to form the outer cylinder 2.

美観が高まる。In the silencer manufactured by the above method, when forming the outer cylinder 2, both edges of the two flat plates are overlapped on the outer peripheral end surface 3A of the partition plate 8, so that the work of attaching the flat plate 2A is facilitated. Therefore, the roundness and verticality of the outer cylinder 2 are improved. In addition, since there are fewer welding points compared to those manufactured by conventional methods, welding man-hours can be reduced, and by cutting the pre-welding part of the welded part 4C, the outer cylinder 2 has no protrusions and the appearance can be improved. Refreshing,
Improves beauty.
