The air conditioning case has a facing surface that face to the facing wall portion and in which through holes are formed. The air conditioning case has a closed space formed therein on an opposite side of the air passage with respect to the facing surface and communicating with the air passage via the through holes. The through holes and the closed space form a resonator having a predetermined resonance frequency.",
