Abstract
A turntable for a disk storage medium includes disk mounting section, shaft center boss and ribs. The disk mounting section includes disk mount surface, center boss and inner side surface. The disk mount surface is used to mount the disk medium thereon. The center boss has an outer side face that engages with a center hole of the disk medium. The inner side face defines a space that has a center axis aligned with that of the center boss. The shaft center boss includes an outer side face and a hole into which a rotating shaft is inserted so as to transmit a driving force to, and rotate, the disk medium. The ribs join the outer side face of the shaft center boss and the inner side face of the disk mounting section together so that through holes are formed between these side faces.
