は構造。Two parts of the support shaft spaced apart from each other in the axial direction are supported on a supported body via bearings, and these bearings are lubricated with lubricating oil so that the support shaft and the supported body are rotated relative to each other. A fitting groove is formed on the circumferential surface of the portion of the support shaft protruding from one of the bearings, and the thrust bearing rotatably fits the plate into the fitting groove, and the thrust bearing rotates the plate. The structure of the thrust bearing of the spindle is characterized in that the thrust bearing is covered with a cover, and the plate and the cover are fixed to the supported body.
