    摘要： An exhaust device includes an exhaust pipe connected at its upstream end to a cylinder head of the engine and an exhaust muffler connected to the downstream end of the exhaust pipe for suppressing the generation of noise from a heat insulating cover that covers a part of the exhaust pipe. A heat insulating cover covers a portion of the exhaust pipe near the engine and a stay is fixed to the heat insulating cover. The stay includes a supporting plate portion curved so as to partially surround the outer circumference of the exhaust pipe. A first vibration isolating member is provided that is sandwiched between the outer circumference of the exhaust pipe and the supporting plate portion, a band member is tightened to mount the supporting plate portion to the exhaust pipe, and a second vibration isolating member is sandwiched between the supporting plate portion and the band member.

    摘要： A muffler structure capable of suppressing generation of abnormal noise in the muffler even when the outer and the inner tubes expand thermally. Provided is a double-pipe muffler structure including an inner tube and an outer tube. In the muffler structure, an annular front step portion and an annular rear step portion are formed in the inner tube, while the step portions is brought into contact, from inside, with the outer tube and thus are supported by the outer tube. The outer tube supports the front and the rear step portions by being brought into close contact with the step portions partially and elastically.

    摘要： A high-performance exhaust silencer in which a shell wall includes a shell outer plate, a shell inner plate, and a damping material to be inserted therebetween. A space between the shell outer plate and shell inner plate of the exhaust silencer is narrowed and the shell outer plate and the shell inner plate will not interfere with each other. An outer shape of the exhaust silencer is small but the expansion chambers are large by providing an air space between the shell outer plate and the shell inner plate. For the above-mentioned damping material, a material obtained by stretchably weaving metal wire into mesh is used.

    摘要： An exhaust muffler system for use on a motorcycle or four-wheeled vehicle provides for operation in either of two modes, a regular configuration that provides a high degree of noise reduction, or a racing specification that provides for a freer-flowing exhaust. Without changing the main body of the muffler, an operator can choose between a quieter, public road setting or a louder, high performance setting. The muffler is provided with two interchangeable spark arresters, and a main body having multiple expansion chambers therein, defined by bulkheads. When a regular spark arrester is installed, exhaust gas passes through one bulkhead three times, greatly reducing the noise produced. With the spark arrester removed, the exhaust gas passes straight through to the open air, enhancing performance. A seal is provided between the bulkheads and the spark arrester, which provides for extension or retraction in the lengthwise direction of the tail pipe.
