<p>PROBLEM TO BE SOLVED: To provide an air ejection device that can change an ejecting direction of air from moment to moment without changing a direction of a main body.SOLUTION: The air ejection device has a chamber body 30 having a chamber CH formed and a nozzle body 40 arranged in the chamber CH. The chamber body 30 has a nozzle hole 37 and air introducing holes 32A and 32B that introduce air into the chamber CH. The nozzle body 40 has a spherical-shaped contact part contacting a peripheral edge part of the nozzle hole 37, a nozzle part 42 and an impeller blade member 50. The impeller blade member 50 receives air and rotates the nozzle body 40 while making the body 40 revolve. The diameter of the nozzle hole 37 is set smaller than a predetermined diameter, so that the contact part of the nozzle part 42 can be closely contacted with the peripheral edge of the nozzle hole 37 and the nozzle body 40 can be revolved and rotated by pressure of the air introduced into the chamber CH.</p> |
