<P>PROBLEM TO BE SOLVED: To provide an air blower capable of surely controlling the direction of wind corresponding to the distribution of wind speed at an air blowing port. <P>SOLUTION: This air blower comprises at least an air blasting fan, an air blasting circuit and at least a sheet of left and right wind direction changing blade for controlling the left and right wind direction at a blowout port of the air blasting circuit. A left and right wind direction changing board 12 has a long depth at a central part of high wind speed and relatively has a short depth at a vertical side of low wind speed. Whereby the air blowing resistance at a longitudinal side and that at a lateral side are balanced, and the direction of the wind blown out from the blowout port 3 into a room is surely changed left and right in accordance with the direction of the left and right wind direction changing board 12 to provide a comfortable space. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
