られることを特徴とする排気音可変マフラ。 In a muffler in which an exhaust gas distribution pipe consisting of an exhaust gas introduction pipe and an exhaust gas discharge pipe is disposed in the shell, and an expansion chamber and a resonance chamber are formed between the exhaust gas distribution pipe and the shell, a partition wall between the expansion chamber and the resonance chamber is used. A resonance tube is installed in the resonance tube, and a valve is provided that opens and closes the flow of exhaust gas to the resonance chamber by operating an actuator facing the outlet of the resonance tube, and the tone of the exhaust sound can be changed by opening and closing the valve. Variable exhaust sound muffler.
