Abstract
An electric fan includes a fan base (), a bearing () and a rotor assembly (). The fan base forms a central tube () receiving the bearing therein. The rotor assembly includes a fan hub (), and a pivot axle () joined to the fan hub. The pivot axle pivotably extends into the bearing. A sealing lid () is screwedly mounted on a bottom opening of the central tube to prevent lubricant oil contained in the central tube from leaking. The sealing lid abuts against a bottom of the bearing to prevent the bearing from deflection.
