摘要：PROBLEM TO BE SOLVED: To provide a fan motor and an oil leakage prevention bearing system capable of preventing the leakage of a lubricant from a clearance between a rotor shaft and an oil leakage preventing cover, and to provide the oil leakage preventing cover in the bearing system. SOLUTION: This oil leakage prevention bearing system includes a bearing 112 having a through hole at its central portion, the oil leakage preventing cover 118 mounted at the upper part of the bearing 112 and having a through hole at its central portion, and the rotor shaft 120 rotatably penetrated through the through hole of the oil leakage preventing cover 118 and the through hole of the bearing 112. A first guide groove 1182 is formed on the bottom face of the oil leakage prevention cover 118 in a state of being approximately radially extending from the center of the bottom face, and the lubricant dispersed from the rotor shaft 120 is radially guided.
