PROBLEM TO BE SOLVED: To fill a predetermined amount of lubricant at the inside of a bearing without generating drawing of a liquid and dropping off of the liquid. SOLUTION: The device for sealing a predetermined amount of lubricant in the bearing having an inner diameter of 6 mm or less is provided with a delivery mechanism for capable of delivering a predetermined amount of lubricant to the inside of the bearing; an excitation mechanism (coil 24, amplifier (amplifier) 26, excitation unit 28 and controller 30) for exciting the delivery mechanism at a predetermined period. A delivery port M for delivering the lubricant to the inside of the bearing is provided on the delivery mechanism and after a predetermined amount of lubricant is delivered from the delivery port, the delivery mechanism is excited by the excitation mechanism in a predetermined period when the delivery port and the bearing are relatively separated from each other.
