The present invention relates to a high-performance electric fan of a 360 degree rotation type and, more specifically, to an electric fan of a 360 degree rotation type attached to the ceiling with an improved structure where the electrodes of a power connecting member for supplying power to a ventilating means are not exposed to the outside, which can: prevent a variety of short circuits caused by exposure to the outside; improve the mutual connecting structure between the rotating shaft of a first driving means and the main rotating shaft to prevent vibration from being transferred from the ventilating means to the speed reducer; place a reverse rotation preventing unit on the main rotating shaft; prevent a trouble of the speed reducer due to reverse rotation and transfer of vibration; and extend the general life of the rotation-type electric fan and make the structure easier for replacement and repair. |
