音器。 The interior of the porous inner cylinder 5, which has an annular sound-absorbing chamber 3 formed on its circumferential surface and a front-end sound-absorbing chamber portion 8 through which an air guide pipe 9 is passed, is partitioned by a sound-absorbing wall plate 10 and a sound-insulating wall plate 13 for expansion and diffusion. A sound absorption chamber 11, an intermediate diffusion sound absorption chamber 14, and a rear diffusion sound absorption chamber 15 are formed, and an interference cylinder 17 having an opposing throttle hole 19 near the closed end 16 is arranged eccentrically in the expanded diffusion sound absorption chamber 11. The open end 18 of the interference cylinder 17 is pierced through the sound absorption wall plate 10,
In addition, a diaphragm tube 20 is disposed in the intermediate diffusion sound absorption chamber 14 at a position opposite to the interference tube 17, and the other end of the diaphragm tube 20 is attached to the sound insulating wall plate 13. This silencer for a small engine has a discharge pipe 21 which is shifted in position so that one end faces deeply into the rear diffusion sound absorption chamber 15 and is installed through a rear end closing plate part 12 of a porous inner cylinder.
