<P>PROBLEM TO BE SOLVED: To provide an electric fan having a simple structure to enable oscillation movement by eliminating a complex mechanical structure for oscillation, without requiring a strut or a support unit on a flat plane which has been an essential component in a conventional electric fan. <P>SOLUTION: In an outer hull 300 in which a front guard 301 and a rear guard 302 are fixed with a guard fixing unit 305, a rotatable weight 100 for generating gyration and a fan 200 are contained, and they are immovably fixed on a motor rotation shaft 19 and rotated by a rotation drive unit 10. A battery 20 as a power source is arranged with a proper balance to the rotation drive unit, and effects start/stop by a switch 314. The gravity center of the rotatable weight 100 for generating gyration is positioned on the rotation shaft, and the fan 200 has a structure making the direction variable by gyration generated by rotation of the rotatable weight for generating the gyration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
