るデイスクチヤツキング機構。 In a disk chucking mechanism that attaches a disk-shaped storage medium to a spindle shaft of a drive device,
The tip of the spindle shaft is formed into a tapered shape, and the center hole of the storage medium into which the spindle shaft is inserted has openings at both ends that have a diameter larger than the diameter of the spindle shaft, and the other central portion that is the center hole of the storage medium into which the spindle shaft is inserted. The hole is formed to have approximately the same diameter as the hole, and the slope from the opening to the center changes in two steps with a shape that is gentler than the tapered surface at the tip of the spindle shaft, and the center hole is inserted into the spindle shaft. A disk chucking mechanism characterized in that the opening of the center hole abuts against the tapered surface of the tip of the spindle shaft and guides it to the center.
