Abstract

PURPOSE: To absorb vibrational energy with no need of applying vibration absorbing material over the entire inner wall surface of a muffler constituting cylindrical member and to thereby prevent occurrence of noises from the muffler, by interposing a band-shaped resilient material between the inner surface of said cylindrical member and the outer peripheral surface of support members which divide the inner space of said cylindrical member into a plurality of chambers.
CONSTITUTION: In a muffler, which comprises a cylindrical member 10 consisting of two semi-cylindrical portions 11a, 11b and three support members 20aW20c disposed in the cylindrical member 10 and having respectively a ring-shaped portion 21 around their outer periphery and which is divided into three chambers R1WR3 by the three support members 20aW20c, one end of a first diffuser pipe 41 connected to exhaust pipe 30 is opened in chamber R1, and opposite ends of a second diffuser pipe 42 are opened respectively in chambers R2 and R3. In the above arrangement, resilient members 50, 50 of glass wool, asbestos or the like shaped in the form of a band are interposed between the ring-shaped portions of support members 20a, 20b and mating recessed portions of the cylindrical member 10, so as to effectively absorb vibrational energy caused by pulsation of exhaust gas flow or by other reasons.
