イプ１０を通って外部に放出される。By the way, in the exhaust muffler M, from the gap between the inner peripheral surface of the rear end of the muffler body 1 and the outer peripheral edge of the tail plate 6,
When the exhaust gas inside the muffler body 1 leaks to the outside, the passing of the leaked exhaust gas causes fading and discoloration of the rear edge of the muffler body 1, which quickly reduces the commercial value of the exhaust muffler M and shortens its lifespan. In addition, there is a problem that the amount of exhaust gas passing through the gap gradually increases and deteriorates the original function of the exhaust muffler M. Therefore, it is desirable to prevent the leakage of exhaust gas as much as possible, but the purpose of the present invention is as follows. This can be achieved by the action of In other words, in order for the exhaust gas in the second silencing chamber C to leak from between the inner peripheral surface of the rear end of the muffler body 1 and the outer periphery of the tail plate 6, the exhaust gas in the second silencing chamber C must be welded and joined as a first step. passing through the section 15 or 17 into the first expansion chamber E, and further into the expansion chamber E;
As a second stage, the exhaust gas must pass through the welded joint 16 into the second expansion chamber E, and must also pass through the welded joint 18 as a third stage. During the above process, the pressure gradually decreases and energy is lost, and due to the so-called labyrinth effect, leakage of exhaust gas from between the rear end edge of the muffler body 1 and the outer peripheral edge of the tail plate 6 is almost eliminated, and the exhaust gas is is discharged to the outside through the tail pipe 10 from the second muffling chamber.

延長も図ることができる。As is clear from the above embodiments, according to the present invention, the outer circumferential edges of the seal separator welded to the inner circumferential surface of the rear end of the muffler body, the outer circumferential edges of the tail and the grate, and the inner surface of the tail plate thereof are respectively attached. A first hermetic expansion chamber is formed between the tail plate and the seal separator by welding, and the winding end of the ring is welded to the outer periphery of the tail plate to form a space between the winding portion and the outer periphery of the tail plate. Second
A closed expansion chamber is formed, and a tail pipe is lightly press-fitted into the muffler body through the rear support hole in the center of the tail plate, and the rear end of the tail pipe is welded to the inner surface of the rear support hole. The exhaust inside the muffler body passes between the inner surface of the rear end of the main body and the outer periphery of the tail plate.
As described above, there are three welded joints and a first welded joint formed between the three welded joints. While passing through the second two expansion chambers, the pressure is attenuated and loses energy, which is hardly released to the outside. The finished part will not fade or change color due to being immersed in exhaust gas, and the commercial value of the exhaust muffler will not be prematurely lowered, and its lifespan can be extended.
