ABSTRACT:
A roller thrust bearing structure rotatably supports a spindle shaft on a frame and includes a circular table which is fixed to the spindle shaft as a flange. A radial bearing is fixed on the frame for rotatably supporting the spindle shaft in a radial direction of the spindle shaft. A support member is located between the table and the frame for rotatably supporting the table on the frame so as to support the spindle shaft in a thrust direction of the spindle shaft. The thrust direction is perpendicular to the radial direction of the spindle shaft. The roller thrust bearing structure for a spindle shaft is used in a thin disc drive.
