ABSTRACT:
A ceiling fan includes auxiliary vanes pivotally connected to the opposite ends of its main vanes, wherein each auxiliary vane is pivotally connected to a common bracket unit through a pull rod at its opposite end to the main vanes. The bracket unit is capable of moving up and down in accordance with the rotating direction of an electric motor along a shaft supporting the body of the fan on a ceiling. By operating a solenoid the bracket unit is connected to or disconnected from the motor. Thus the auxiliary vanes are rotated in a clockwise direction or a counter-clockwise direction, thereby changing the angle of attachment thereof to the main vanes as desired while the main vanes are in rotation.
