ンの消音装置。In an engine silencer, a silencing chamber is provided in a pipe that communicates with a combustion chamber of an engine, and the sound in the pipe is attenuated in the silencing chamber through a resonance hole provided in the pipe, in which the opening of the resonance hole is variable. An engine muffling device, characterized in that it is provided with a control mechanism that changes the opening of the resonance hole in proportion to the negative pressure acting on the muffling chamber.
