Abstract
An oil-retaining bearing fan structure includes a fan base seat, an oil-retaining bearing and a fan impeller. The fan base seat has a bearing cup on one side. At least one magnetic member is enclosed in the bearing cup. The magnetic member serves to apply a magnetic attraction force to a shaft of the fan structure to make the shaft quickly restore to its optimal operation position so as to reduce wear and lower the noises and vibration of the fan structure in operation. Therefore, the lifetime of the fan structure can be prolonged.
