a spindle 23 protruding from the center of the rotary table 11 so as to be inserted into the drive pin 25 and a drive pin 25 inserted into the drive pin insertion hole 10b with a margin.
and a support 24 that supports the drive pin 25 so that the drive pin 25 can be displaced at least in the axial direction, the drive pin 25 is coupled to at least the support 24. A nearby portion is made of a magnetic material, or a magnetic member 24 is provided below the drive pin 25.
a are connected, and the drive pin 25 is inserted into the drive pin insertion hole 10b.
in the vicinity of the coupling or the magnetic member 24 so as to obtain the biasing force in the axial direction for insertion into the magnetic member 24.
A disk device characterized in that a magnet 29 that attracts a is arranged. (2) 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 has a certain positional relationship with the spindle insertion hole 10a. In order to rotationally drive the recording medium disk 2 in which the drive pin insertion hole 10a is provided in the hub 2b, a rotary table 11 and the spindle insertion hole 10 are provided.
a spindle 23 protruding from the center of the rotary table 11 so as to be inserted into the drive pin 25 and a drive pin 25 inserted into the drive pin insertion hole 10b with a margin.
and the drive pin 25 is arranged so that the drive pin 25 can be displaced at least in the radial direction of the disk 2.
5, at least a portion of the support 24 near the connection of the drive pin 25 is formed of a magnetic material, or a lower part of the drive pin 25 is made of a magnetic material. Member 24
a is connected to the rotating table 11, a rotor of a motor having a magnet integrally formed therein, a stator winding arranged to face the magnet of the rotor, and an attractive force of the magnet. Therefore, the portion near the coupling or the magnetic member 24a and the magnet 29 are related to each other so that the biasing force in the axial direction for inserting the drive pin 25 into the drive pin insertion hole 10b is obtained. Characteristic disk device. (3) Furthermore, the magnet 29 applies a biasing force to the support body 24 in a direction outward from the center of the disk 2.
A disk device characterized in that the portion near the coupling or the magnetic member 24a and the magnet 29 are related to each other as given by.
