CLAMP MECHANISM OF MAGNETIC DISK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a clamp mechanism of a magnetic disk device capable of suitably setting pressurizing force to a magnetic disk and easily exchanging the magnetic disk. SOLUTION: In the magnetic disk device, a placing part 9a extending from a lower end on the outer peripheral side of a hub 12 rotated around a spindle shaft 3 to a radial direction is formed at the hub 12 and a magnetic disk 11 is pressurized and fixed by the clamp 15. The clamp 15 is formed in a nearly annular shape and fitted in a cylindrical trunk part 10a formed at the hub 12 and the outer peripheral side of the clamp 15 is made to abut against the magnetic disk 11. A male screw part 10b is formed on the periphery of the trunk part 10a of the hub 12 and screwed with a nut 16 on the inner periphery of which a female screw part 16a is formed. The clamp 15 is pressurized in the magnetic disk 11 direction and the magnetic disk 11 is pressurized and energized to the placing surface of the hub 12 by the clamp 15 by screwing the nut 16 with the trunk part 10a of the hub 12.
