摘要

PROBLEM TO BE SOLVED: To provide an injection method of lubricant to a fluid bearing apparatus in which the injection of the lubricant is easy and bubbles are hard to be trapped into a fluid bearing clearance. SOLUTION: The fluid bearing apparatus comprises a shaft 13, a sleeve 12 facing with the shaft 13 by way of a fluid bearing clearance, and a through hole 13a penetrating through the shaft 13 axially.
