Abstract
A fan shaft structure includes a fan frame having an axle seat set therein with a stator silicon steel sheet set and a circuit board installed outside the axle seat, a fan blade set in the fan frame holds a rotor magnet therein relative to the outside of the stator silicon steel sheet set, and a rotating shaft has one end assembled at the fan blade and its other end assembled in the axle seat. The outer part of the rotating shaft located in an accommodating groove is mounted with bearings, oil-containing members and oil-retaining caps. The oil film on the inner diameter of the oil-containing members can contact the rotating shaft to fill the gap between the oil-containing members and the rotating shaft, which can prevent external environmental dust, fine particles or foreign matter from penetrating between the rotating shaft and the bearings.
