<p>PROBLEM TO BE SOLVED: To provide an air blowing device where a wind direction is controlled to be in various directions with a simple structure and without having a fin to control the wind direction at an air blowoff port.SOLUTION: An air blowing device comprises: a blowoff cylindrical body (13) which has an air blowoff port (12) on a peripheral wall part to blow out introduced air introduced from both open ends to inside, and where a pair of inner wall surfaces (13p and 13q) in a vertical direction with the air blowoff port (12) as a border extend so as to approach each other toward the front in a blowoff direction of the introduced air; first and second ducts (19 and 21) which is connected to both sides with the air blowoff port (12) as a border and where a downstream end is one of the open ends of the blowoff cylindrical body (13); third and fourth ducts (23 and 25) which is connected to both sides with the air blowoff port (12) as a border and where a downstream end is the other of the open ends of the blowoff cylindrical body (13); and air flow control means (11) to individually control air flow amounts from an air flow source (9) to the first to fourth ducts (19, 21, 23 and 25).</p> |
