Claims

[Scope of utility model registration request]

In an intake system expansion type resonator that is installed on the intake side of an air cleaner and muffles intake noise, the resonator main body is divided into a first expansion chamber and a second expansion chamber by a separator, and A first intake pipe is provided that passes through the first expansion chamber and communicates with the second expansion chamber;
A second intake pipe communicating with the expansion chamber is provided, a sound absorbing material covering the punching metal provided on the outer peripheral surface of the first intake pipe is provided to communicate with the first expansion chamber, and the second intake pipe is connected to the first expansion chamber. An intake system expansion type muffler, characterized in that an intake pipe is provided with a gap portion communicating with the second expansion chamber.
