To provide a duct type air blower that can change an amount of blow from an air outlet while standardizing a shape of an air outlet member, and can be manufactured simply at low cost.SOLUTION: A duct type air blower 1 includes: cylindrical duct enclosures 31, 41 for forming duct members; a screw member 7 disposed in the duct enclosures 31, 41; spiral flow paths 34, 44 formed by the screw member 7, and spirally rotating air in the duct enclosures 31, 41; and a first air outlet 11 to a fourth air outlet 14 provided in the longitudinal direction of an outer circumferential part of the duct enclosures 31, 41, and blowing the air and arranged optionally. Multiple openings 5 are formed in a slit-like shape for each of the first air outlet 11 to the fourth air outlet 14 in the circumferential wall of the duct enclosure 31. An air outlet member 8 with a discharge opening 83 is mounted in the outside of the circumferential wall of the duct enclosure 31 by covering the circumference of the opening 5. The slit widths W1-W4 of the openings 5 are set according to the amount of blow of the air.SELECTED DRAWING: Figure 1 【課題】吹出口部材の形状を統一しつつ、吹出口からの吹出量を変化させることができ、低コストで且つ簡単に製造することができるダクト型送風装置を提供する。【解決手段】ダクト型送風装置１は、ダクト部材を形成する円筒状のダクト筐体３１，４１と、ダクト筐体３１，４１内に配されるスクリュー部材７と該スクリュー部材７によって形成されダクト筐体３１，４１内の空気を螺旋回転させる螺旋流路３４，４４と、ダクト筐体３１，４１の外周部の長手方向に設けられ空気を吹き出す任意に配列された第１吹出口１１〜第４吹出口１４と、を備える。開口５は、ダクト筐体３１の周壁に、第１吹出口１１〜第４吹出口１４ごとにスリット状に複数形成される。ダクト筐体３１の周壁の外側に、空気吹出口８３を備える吹出口部材８が開口５の周囲を覆って取り付けられる。開口５のスリット幅Ｗ１〜Ｗ４は、空気の吹出量に応じて設定される。【選択図】図１
