磁気デイスクチヤツキング機構。 A magnet for attracting the metal hub is provided on the upper surface of a spindle hub for holding a magnetic disk having a metal hub in the center, and a drive pin is provided protruding from a leaf spring provided on the lower surface of the spindle hub,
The drive pin is inserted through a drive pin protrusion opening formed in the spindle hub and inserted into a drive hole formed in the metal hub, and the spindle shaft protruding from the center of the spindle hub is inserted into the metal hub. A magnetic disk chucking mechanism that fixes the magnetic disk to the spindle hub by inserting the magnetic disk into a center hole provided in the spindle hub and rotating the drive pin within the plane of the leaf spring around a rotational fulcrum of the leaf spring, One side of the drive pin protruding opening on the side of the rotational fulcrum of the leaf spring is formed into a curved part that is concentric with the rotation locus of the drive pin around the rotational fulcrum of the leaf spring, and the outer circumference of the drive pin A magnetic disk chucking mechanism is characterized in that it is in constant contact with this curved portion.
