To provide a resonator structure that can deaden noise with different frequency bands while suppressing increase of volumes of an intake housing.SOLUTION: When an inside/outside air switching door (120) is at a first position at which a first inside air introduction port (103) is closed and an inside air door (130) is at the first position at which the first inside air introduction port (103) is closed, a first resonator is formed of a resonator formation space (106) in which a first opening end (106a) is opened by a first opening-end blocking element (121) of the inside/outside air switching door and a second opening end (106b) is blocked by a second opening-end blocking element (131) of the inside air door; and when the inside/outside air switching door is at a second position at which an outside air introduction port (102) is blocked and the inside air door is at the second position at which the second inside air introduction port is opened, a second resonator is formed of a resonator formation space in which the first opening end is blocked by the first opening-end blocking element and the second opening end is opened by the second opening-end blocking element.SELECTED DRAWING: Figure 3

    【課題】インテークハウジングの容積拡大を抑制しつつ、異なる周波数帯域の騒音を打ち消しうるレゾネータ構造の提供【解決手段】内外気切替ドア(120)が第1内気導入口(103)を閉塞する第1の位置にあり、内気ドア(130)が第1内気導入口(103)を閉塞する第1の位置にあるときに、内外気切替ドアの第1開放端閉塞要素(121)により第1開放端(106a)が開放されるとともに内気ドアの第2開放端閉塞要素(131)により第2開放端(106b)が閉塞されたレゾネータ形成空間(106)により第1レゾネータが形成され、内外気切替ドアが外気導入口(102)を閉塞する第2の位置にあり、内気ドアが第2内気導入口を開放する第2の位置にあるときに、第1開放端閉塞要素により第1開放端が閉塞されるとともに第2開放端閉塞要素により第2開放端が開放されたレゾネータ形成空間により第2レゾネータが形成される。【選択図】図3
