Abstract
A fan structure including a center portion, multiple fan blades, and a fixing ring is provided. The center portion includes a bottom surface and a center shaft. The center shaft is perpendicular to the bottom surface, and the direction in which the center shaft extends is an axial direction. The fan blades are mutually separated and connected to the bottom surface of the center portion and are disposed around the axial direction. Each of the fan blades has a height which is parallel to the axial direction. The fixing ring simultaneously contacts the side of the fan blades which is away from the center shaft. Along the axial direction, with the bottom surface of the center portion as a reference surface, the fixing ring is disposed at a range of 40% to 80% of the height of each of the fan blades.
