The invention provides an anti-fracture fan structure including a hub, a plurality of blades, and a plurality of ribs. The hub has an inner surface formed inside and encircling it. The plurality of blades are arranged outside and around the hub. The plurality of ribs projects from the inner surface of the hub into the inside of the hub. Each of the plurality of ribs is not perpendicular to the inner surface of the hub. Furthermore, the anti-fracture fan further includes a shielding-can situated inside the hub and in contact with the plurality of ribs. Moreover, the hub can be formed of a plastic material and the shielding-can can be formed of a metal material. The ribs can be easily warped when the shielding-can expands. |
