いうことが行われている。2. Description of the Related Art Conventionally, in an internal combustion engine for a vehicle, when the exhaust passage cannot be provided with a sufficient length due to its arrangement on the vehicle body, the high temperature of the exhaust gas acts on the carbon particles contained in the exhaust gas. Since sparks generated as a result may scatter outward from the tail pipe of the exhaust muffler, a spark arrester is installed in the exhaust muffler for the purpose of preventing this.

果を奏するものである。The spark arrester installed in this muffler is one in which a cylindrical metal pipe is integrally fixed by spot welding or the like to the large-diameter portion of the rear end of a slender conical screen made of metal mesh such as stainless steel. The end of the screen is inserted from the tail pipe end of the muffler so as to face the upstream direction of the exhaust gas passage, and the pipe part welded to the rear end of the screen is fitted and locked to the tail pipe of the muffler. It is supported in a cantilever manner in the muffler, and the effect that all of the exhaust gas passes through the screen of the spark arrester so that the sparks are extinguished.

ものになるという問題があった。However, in such a case, in manufacturing the screen, the spot electrode must be inserted inside the elongated conical cylindrical body, the spot electrode is easily deformed, and cooling is required. Since it becomes necessary to insert the spot welding, the work of spot welding becomes difficult, and since it is difficult to work by spot welding to close the tip of the conical tubular body, the bent part is joined by brazing. However, there is a problem in that the manufacturing cost becomes high.

う問題がある。However, in the known spark arrester as described above, the flange 22 where the tip of the screen 2 made of wire mesh is overlapped is simply closed by spot welding, so that the product is handled and the muffler is handled. It is dangerous that the cut surface of the wire mesh comes into contact with the hand when it is assembled, and the wire mesh cut surface at the tip portion is liable to be ripped off. Also, the joint flange portions 21 on both long sides bent in the longitudinal direction of the screen are rear ends. Since the bending is fixed only at the pipe portion 3 of the above, there is a problem that the bending state returns due to the springback action of itself and the joint flange portion 21 separates from the wall surface of the screen and projects.

More specifically, there is no risk of the cut surface of the wire mesh coming into contact with the hand when handling or assembling to the muffler, there is no wrinkling at the tip, and the bent state of the joining flange part depends on its own springback action. It is an object of the present invention to provide a spark arrester that does not return to its original state, is easy to manufacture, can reduce the number of spot welding steps, and can reduce the manufacturing cost.

Is a fan-shaped blank 1 of wire mesh as shown in FIG.
As shown in FIG. 6, (A) the fan-shaped blank 10 is folded in two in the radial direction, and the flange portions 11a and 11b on both edges in the radial direction are overlapped with each other.
After joining by spot welding at the welding point 12 of the location, (B) the portion other than the joining flange portion 11 is expanded into a conical tubular shape, and the joining flange portion 11 protruding from the conical tubular portion 13 is conical. A long and narrow cone whose front end is closed by bending along the wall surface of the tubular portion 13 and bending the tip portion 14 of the conical tubular body including the (C) joining flange portion 11 toward the front and then crushing it. It is formed as a screen 2 in the shape of a circle.
