Stage: PROBLEM TO BE SOLVED: To provide a suction device that stably forms an air curtain for enclosing a wide range, can efficiently suck the enclosed range by a tornado flow, and has excellent manufacturing easiness and designability.SOLUTION: A suction device for performing local exhaust includes: a suction flow passage 10 that has a suction port in the end in a direction of a suction object 90 and allows a suction flow to flow; a suction fan 20 for generating a suction flow in the suction flow passage 10; a blow-off flow generation chamber 30 for introducing a blow-off flow from an inlet in a side opposite to the suction object 90 and expanding it in a disk shape; multiple blow-off fans 40 for blowing off the blow-off flow in an outer direction whirled round with the axis of the suction flow passage 10 as a center from the blow-off flow generation chamber 30; and a blow-off flow deflection guide 50 for deflecting a blow-off flow blown off by the multiple blow-off fans 40 in a direction of the suction object 90.SELECTED DRAWING: Figure 1 (Grant)
