吸入口２３から上段ダクト部分２７を通つて排出
口２４の上部に至る第１空気通路２８と、下段吸
入口２５から下ダクト部分２９を通つて排出口２
４の下部に至る第２空気通路３０とが形成され
る。 Therefore, the duct body 21 is provided with two upper and lower suction ports 23 and 25, and the first air passage extends from the upper suction port 23 through the upper duct portion 27 to the upper part of the discharge port 24. 28 and the discharge port 2 from the lower suction port 25 through the lower duct portion 29.
4 is formed.
上段吸入口２３の吸入開口面積S1と下段吸入口
２５の吸入開口面積S2の和は、適正な換気効率を
得るための有効な吸入開口面積Ｓとほぼ同じに設
定する（Ｓ≒S1＋S2）。 The sum of the suction opening area S 1 of the upper suction port 23 and the suction opening area S 2 of the lower suction port 25 is set to be approximately the same as the effective suction opening area S to obtain appropriate ventilation efficiency (S≒S 1 + S2 ).
上記のようにエアアウトレツトダクト２０を構

されているので、適正な換気効率が保障されるの
である。 At this time, even if the rear pillar 12 (hollow portion 15) is thin with a small cross-sectional area and the cross-sectional area of the duct body 21 must also be made small, the suction opening area of the upper suction port 23 and the lower suction port 25 may be reduced. Sum (S 1
+S 2 ) is set to be approximately the same as the effective suction opening area S, thus ensuring appropriate ventilation efficiency.
また、洗車時等に外グリル１８、排出口２４を
介してダクト本体２１内に水等が浸入した場合に
は、水等は隔壁２６でガイドされてスムースに車
外へ排出され、内部に溜まることはない。 Additionally, if water or the like enters the duct body 21 through the outer grille 18 or the discharge port 24 during car washing, etc., the water or the like will be guided by the partition wall 26 and smoothly discharged to the outside of the vehicle, and will not accumulate inside. There isn't.
