<P>PROBLEM TO BE SOLVED: To form an accurate dynamic pressure generating part at low cost. <P>SOLUTION: The dynamic pressure generating part for generating a dynamic pressure action in a clearance between bearings is formed on the outer peripheral surface 2a of a material 2' forming a shaft part 2. In this case, an ink 12 is supplied in the state of a plurality of materials 2' axially connected to each other to form the dynamic pressure generating part of the assembly of the ink 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
