BEARING MEMBER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To stably and inexpensively provide a bearing member having a highly accurate dynamic-pressure generator. SOLUTION: A bearing member 8 comprises an electroformed part 10 and a molded part 14 molded through the insertion and injection molding of the electroformed part 10. A radial bearing surface A having a dynamic-pressure generator for generating fluid dynamic pressure in a radial bearing clearance is formed in the electroformed part 10. COPYRIGHT: (C)2007,JPO&INPIT
