<p>PROBLEM TO BE SOLVED: To provide an electric fan oscillation mechanism having a superior design characteristic in which the maximum oscillation angle of the electric fan main body is not restricted by a size of the oscillation mechanism.SOLUTION: A helical gear 20 is co-axially arranged with a rotating shaft for oscillation turning of an electric fan main body comprising a fan motor 10 and a blower fan 12. A helical gear 22 fixed to the rotation shaft of the oscillation motor 24 is engaged with the helical gear 20, the oscillation motor 24 is connected to the electric fan main body through a connecting member 14, the oscillation motor 24 is rotated in a normal rotation or reverse rotation to cause the helical gear 22 to move to or back around the helical gear 20 together with the oscillation motor 24 and rotated and to cause the electric fan main body connected to the oscillation motor 24 to be oscillated and rotated.</p> |
