摘要:
A method of manufacturing a fluid dynamic bearing in which a stopper is fixed by welding. The bearing comprises a hub, a shaft erected on the hub, a sleeve, a cylindrical wall erected on the hub, and the stopper mounted on the cylindrical wall. The method comprises a first step to hold oil in the bearing gap, and a second step to locate the stopper on the peripheral wall being apart from the interface of the oil to fix the stopper by LASER welding.

A housing member for use in a disk drive apparatus includes a rectangular bottom portion and a side wall portion arranged to extend upward from an outer circumferential portion of the bottom portion. The side wall portion includes four outside surfaces including a first outside surface and a second outside surface perpendicular or substantially perpendicular to the first outside surface. The first outside surface includes a first cutting base region. The second outside surface includes a second cutting base region. The bottom portion includes a bearing fixing portion arranged to fix a bearing mechanism of a motor arranged to rotate a disk.
