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 resonant tube is installed that allows the bearing provided in the resonant tube to be slid by the operation of an actuator, and the resonant tube has an opening hole that is hidden by the bearing when the bearing slides, and the opening hole is hidden by the bearing. A variable exhaust sound muffler characterized by having a variable exhaust sound resonance chamber that changes the resonance frequency of the resonance chamber by opening and closing the cover, thereby changing the tone of the exhaust pipe.
