ディスク駆動装゛ 置。(1) Consisting of a hub 2b and a recording medium sheet 2a fixed to the hub 2b, a spindle insertion hole lea is provided approximately in the center of the hub 2b, and has a certain positional relationship with the spindle insertion hole 10a. A drive protrusion insertion hole 10b is provided in the hub 2b, and the drive protrusion insertion hole 10
b is an edge 30 whose distance from the spindle insertion hole 10a becomes shorter as the hub 2b progresses in the normal rotation direction;
In order to rotationally drive the recording medium disk 2 having a rotary base 11, a spindle 12 protruding from the center of the rotary base 11 so as to be inserted into the spindle insertion hole 10a, and the drive protrusion insertion hole. 10b with a margin, a leaf spring 15 supporting the driving projection 13 so that the driving projection 13 can be displaced in the axial direction and in the approximately radial direction of the disk 2; a rotational drive mechanism coupled to the rotary table 11, and an edge 30 of the drive protrusion insertion hole 10b is connected to the drive protrusion 13.
In a disk drive device configured to hold the drive protrusion 13 at a fixed position in the drive protrusion insertion hole 10b by pressing the drive protrusion 13 in a substantially radial direction of the disk 2, the drive protrusion 13 rotates the disk 2. A disk drive device characterized in that a portion for limiting the inclination of the drive protrusion 13 is provided on the side opposite to the side that engages with the hub 2b for driving.
