A fan structure of the present invention has a base having a first supporting piece, a motor stator mounted on the base, a motor rotor defined corresponding to the motor stator, a fan blade having a hub located at a central portion thereof, one end of the hub abutting the first supporting piece. The motor rotor is mounted on an inner wall of the fan blade. An upper cover body covers a periphery of the fan blade, the upper cover body has an oblique resilient portion defined on a top portion thereof, the resilient portion defines a second support piece thereon, and the second support piece abuts another end of the hub. The improved fan structure is a bearingless structure, which can simplify the overall structure, is easy to assemble, effectively reduces manufacturing costs and improves a rotating stability of the hub.
