Abstract
An oil-retaining bearing fan device includes a fan base seat, at least one oil-retaining bearing and at least one magnetic member. The oil-retaining bearing is disposed in a bearing hole of the fan base seat. The oil-retaining bearing has at least one receiving hole for receiving the magnetic member therein. The magnetic member serves to apply a magnetic attraction force to a shaft of the fan device 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 device in operation. Therefore, the lifetime of the fan device can be prolonged.
