| abstract |
PROBLEM TO BE SOLVED: To provide a hydrodynamic bearing device having high reliability and suitable for miniaturization by using a dynamic pressure generating liquid having excellent heat resistance and little evaporation loss. A hydrodynamic bearing device having a dynamic pressure generating mechanism in at least one of a shaft structure and a sleeve, wherein a dynamic pressure generating liquid exists in a gap where the shaft structure and the sleeve face each other. The main component of the dynamic pressure generating liquid has a viscosity index of 150 or more, a surface tension of 35 mN / m or more, and / or 0 ° C. and 80 ° C. of 7.0 × 10 −4 K −1 or less. Hydrodynamic bearing device in which an ionic liquid having an average body expansion coefficient of between is present. [Selection] Figure 1 |
