装置。[Claims for Utility Model Registration] (1) Consisting of a hub 3 and a recording medium sheet 2 fixed to the hub 3, a spindle insertion hole 5 is provided approximately in the center of the hub 3, and the spindle insertion hole 5 and In order to rotationally drive the recording medium disk 1, which has a drive protrusion insertion hole 7 provided in the hub 3 with a certain positional relationship, the rotary base 8 and the rotation protrusion are inserted into the spindle insertion hole 5. The spindle 4 protrudes from the center of the base 8, the drive protrusion 6 is inserted into the drive protrusion insertion hole 7 with a margin, and the drive protrusion 6 is arranged such that the drive protrusion 6 can be displaced at least in its axial direction. In the disk drive device, the rotary table 8 is formed of a plastic magnet 9, and the portion 12 of the drive projection insertion hole 7 in contact with the drive projection 6 is provided with the drive projection 6. A disk drive device characterized in that a material that is more difficult to wear or deform than the plastic magnet 9 is disposed, and this material is integrated into the plastic magnet 9. (2) The driving protrusion 6 comprises a fixing pin 6a implanted in the leaf spring 15, and a roller 6b rotatably attached to the pin 6a.Claim 1 of the Utility Model Registration Claim. Disk drive as described.
