Abstract
A bracket 10 has a U-shaped cross section in which a pair of facing plate portions 15 extend from both side edges of a bottom plate portion 12 so as to face each other, and is fixed to a vehicle body side for mounting a predetermined component. The bottom plate portion 12 and the pair of facing plate portions 15 partition a bracket inner space 16, and the bottom plate portion 12 is provided with a through hole 20 which makes the bracket inner space 16 communicate with an outside. A resonator 23 is fixed to the bracket 10 in a state where the resonator 23 is accommodated in the bracket inner space 16. A ventilation passage 29 makes the resonator 23 communicate with the intake duct 21 through the through hole 20.
Claims2
