Claims

[Claims for Utility Model Registration] Consisting of a hub 2b and a recording medium sheet 2a fixed to the hub 2b, a spindle insertion hole 10a is provided approximately in the center of the hub 2b, and the spindle insertion hole 10a is located at a certain position. In order to rotationally drive the recording medium disk 2, which has a drive pin insertion hole 10a in the hub 2b, the rotary table 11 and the spindle inserting hole 10a are inserted into the spindle insertion hole 10a. A spindle 23 protruding from the center and the drive pin insertion hole 1
A drive pin 25 inserted into 0b with a margin,
It supports the driving pin 25 so that the driving pin 25 protrudes above the rotating table 11 through a hole 27 provided in the rotating table 11, and is elastic in order to provide displacement of the driving pin 25 in the axial direction. and a drive pin support 24 arranged along the lower surface of the rotary table 11 and rotatably supported by the rotary table 11 at a different angular position from the drive pin 25. , the center of the spindle 23 and the drive pin 25
A disk device characterized in that a part 24a of the support body 24 is disposed below the rotary table 11 at or near an extension of an imaginary straight line connecting the center of the disk drive.
