PROBLEM TO BE SOLVED: To suppress and avoid the generation of the wind noise of a suction duct with a resonance silencer.SOLUTION: A suction duct 1 with a silencer is configured so that a duct body 11 making air flow inside and a resonance silencer 12 are integrated and the resonance silencer 12 is branched from the duct body 11. The duct body 11 is provided with a through-hole 15 making the inside communicate with the outside of the suction duct at a position close to a part (a branch part) that the resonance silencer 12 is branched. The through-hole 15 is provided at least upstream or downstream of the branch part. It is preferable to provide the through-hole 15 upstream of the branch part. |
