PROBLEM TO BE SOLVED: To provide an air introduction device which controls a quantity of introduction air and which can be down-sized.SOLUTION: An air introduction device 51 comprises a guide part 40, plate-like members 61, 62, intermediate members 71, 72 and a rotor 81. The intermediate members 71, 72 are provided between plural plate-like members 61, 62 and can be elastically deformed. When the rotor 81 is rotated in one direction, the plate-like members 61, 62 and the intermediate members 71, 72 are moved along the guide part 40 and close flow channels 241 to 243. When the rotor 81 is rotated in the other direction, the plate-like members 61, 62 and the intermediate members 71, 72 are moved along the guide part 40 and open the flow channels 241 to 243, and the rotor 81 takes up the plate-like members 61, 62 and the intermediate members 71, 72. Thus, a quantity of air to be introduced can be controlled and the intermediate members 71, 72 can be elastically deformed, and therefore, the rotor 81 can take up the plate-like members 61, 62 and the intermediate members 71, 72. Consequently, the air introduction device 51 can be down-sized.SELECTED DRAWING: Figure 10
【課題】導入する空気量を制御し、小型化可能な空気導入装置を提供する。【解決手段】空気導入装置51は、案内部40、板状部材61、62、中間部材71、72および回転体81を備える。中間部材71、72は、複数の板状部材61、62の間に設けられ、弾性変形可能である。回転体81が一方向に回転したとき、板状部材61、62および中間部材71、72が案内部40に沿って移動して流路241−243を閉じる。回転体81が他方向に回転したとき、板状部材61、62および中間部材71、72は案内部40に沿って移動して流路241−243を開き、回転体81は板状部材61、62および中間部材71、72を巻き取る。これにより、導入する空気量を制御でき、中間部材71、72が弾性変形できるため、回転体81は板状部材61、62および中間部材71、72を巻き取ることができる。このため、空気導入装置51を小型化できる。【選択図】図10
