Abstract: A bearing oil replenishing structure for fan includes a base of a fan and at least one oil reservoir member. The base includes a hollow shaft barrel upward extended from a central area thereof. The shaft barrel internally defines a bearing receiving hole for receiving a self-oiling bearing therein and is provided on its inner wall surface with at least one sidewall recess. The fan also includes an impeller having a shaft, which is pivotally fitted in the self-oiling bearing. The oil reservoir member is correspondingly fitted in the sidewall recess in the shaft barrel for absorbing extra lubricant oil thrown out of the self-oiling bearing due to a centrifugal force produced by the rotating shaft to therefore always store a proper amount of oil. The stored lubricant oil can be released to replenish the self-oiling bearing timely, enabling the latter to have extended service life.
