PROBLEM TO BE SOLVED: To provide an air curtain generation device capable of suppressing turbulent flow when a work-piece passes through an air curtain.SOLUTION: In an air curtain generation device 20, an air blowing portion 25 and an air suction portion 35 facing a lower side portion than the window 91 of the vehicle body 90 are put in a closed state by a shutter 26 when a vehicle body 90 being a work-piece passes through each air curtain P and the lower side halves of the air curtains P disappear partially. Accordingly, a situation that large turbulent flow is caused by blowing air to the vehicle body 90 is prevented.SELECTED DRAWING: Figure 3 |
