PROBLEM TO BE SOLVED: To increase a production efficiency by facilitating an oil filling operation for filling lubricating oil into a fluid bearing. SOLUTION: This oil filling tool comprises a receiving plate 2 having a plurality of bearing holding parts 3 for holding bearing units 1 and a retaining plate 4 having a plurality of sealed parts 5 for sealing the upper end opening parts 1a of the bearing units 1. The upper end opening parts 1a of the plurality of bearing units 1 held by the bearing holding parts 3 are sealed by the sealing parts 5 of the retaining plate 4, air in the bearing units 1 is bled by atmosphere 10a in vacuum state, and the lower end opening parts 1b thereof are dipped in the lubricating oil and the atmosphere 10a is returned to the atmopheric pressure to fill the lubricating oil from the lower end opening parts 1b into the bearing units 1. Thus the lubricating oil can be filled into the plurality of bearing units at a time. COPYRIGHT: (C)2003,JPO
