Embodiment Construction
[0027] In the following, embodiments of the present invention will be described with reference to FIGS. 1 through 7.
[0028]FIG. 1 conceptually shows an example of the construction of a spindle motor for an information apparatus with a dynamic pressure bearing device 1, supporting a shaft member 2 with a dynamic pressure oil film, incorporated therein. This spindle motor is used in a disc drive device, such as an HDD, and contains the dynamic pressure bearing device 1, a disc hub 3 mounted to a shaft member 2, and a stator coil 4 and a rotor magnet 5 that are opposed to each other through the intermediation, for example, of a radial gap. The stator coil 4 is mounted to the outer periphery of a bracket 6, and the rotor magnet 5 is mounted to the inner periphery of the disc hub 3. As described below, the dynamic pressure bearing 1 has a housing 7 fixed by adhesion to the inner periphery of the bracket 6. The disc hub 3 retains one or a plurality of discs D, such as magnetic discs (see ...
