Abstract
An oil bearing structure of a fan includes a shaft seat, a rotating shaft, and an oil bearing. The shaft seat includes a boss. A middle portion of the boss defines a slot. One end of the rotating shaft is inserted into the slot. Another end of the rotating shaft is a free end. The oil bearing is sleeved on an outer periphery of the rotating shaft. An axis of the rotating shaft and an axis of the oil bearing are perpendicular to the shaft seat. An effective length of the oil bearing and the rotating shaft is 50%-70% of a length of the fan.
