A self-lubrication bearing structure includes a bearing, which is made from a porous material capable of absorbing and transferring a lubricating oil and which has a center axle hole for the passing of the shaft of a motor and multiple oil retaining grooves that retain a lubricating oil, and a casing surrounds the bearing around the shaft of the motor. During rotation of the shaft, the lubricating oil is caused to move out of the porous structure of the bearing to lubricate the shaft. When the rotation of the shaft is stopped, the lubricating oil flows back to the oil retaining grooves.
