PROBLEM TO BE SOLVED: To provide an oil-repellent agent coating device for automatically and uniformly applying an oil-repellent agent on a bearing component with an irregular-shaped inner diameter section wherein the inner diameter is nonlinearly varied in the axial direction. SOLUTION: The oil-repellent agent coating device is constituted of a coating head 10 for coating the oil-repellent agent on a irregular-shaped inner diameter section 5a of the bearing component 5 and an oil-repellent agent feeder 20 for quantitatively feeding the oil-repellent agent to the coating head 10. The coating head 10 is constituted of a main body member 11 formed of a pillar- shaped protrusion 12 having a radial direction jet outlet 14 and fitted with the irregular inner diameter section 5a through a given clearance and an O-ring 13 as a seating section whereon the lower end face 5c of the bearing component 5 is seated liquid-tightly and a holding member 16 for holding the bearing component 5 from outside, and the main body member 11 is provided with a guide passage 15 for guiding the oil-repellent agent from the oil-repellent agent feeder 20 to the jet outlet 14.
