ラ装置。 a muffler having an exhaust gas inlet pipe and an exhaust gas outlet pipe; and an inlet-side vibrator having one end closed and the other open end connected to the exhaust pipe of the engine, and an intermediate portion connected to the exhaust gas inlet pipe. an absorption pipe; and an exit vibration absorption pipe whose one end is closed and whose other open end is connected to a tail pipe, and whose middle portion is connected to the exhaust gas outlet pipe, the entrance vibration absorption pipe being , the volume from the connection part with the exhaust gas inlet pipe to the closed end is set so as to form a resonance chamber that resonates and damps the air column vibrations occurring in the exhaust pipe, and a sound absorbing material such as glass wool is installed in the resonance chamber. The exit-side vibration absorbing pipe is configured such that a volume from the connection part with the exhaust gas exit pipe to the closed end forms a resonance chamber that resonates and damps air column vibrations occurring in the tail pipe. A muffler device characterized in that a sound absorbing material such as glass wool is stored in the resonant chamber.
