ABSTRACT:
The disk-chucking apparatus comprises a chuck base having a fitting hole formed through the center thereof for allowing a driving shaft of the motor, and a plurality of first and second disposition parts formed at the outer surface. A plurality of chuck pins are disposed in the first disposition parts of the chuck base such that the chuck pins can be moved inward and outward, respectively. The chuck pins are resiliently supported outward by means of spring members each having one end connected to the chuck base. A plurality of resilient pieces are provided at the second disposition parts, respectively. Each of the resilient pieces comprises a curved part, formed between a horizontal resilient part and a vertical resilient part, having first and second inner curved sections such that outer surfaces of the resilient pieces resiliently contact the inner circumference of the center hole of the disk.
