Abstract
A chuck pin and a disk chucking device equipped with the chuck pin are disclosed. In accordance with an embodiment of the present invention, the chuck pin fastening a disk by compressing an inner circumference of the disk includes a protruding part, which presses against the disk, and a body, in which a front part of the body is coupled to the protruding part and an inclined part is formed on a lower surface of the body such that the front part of the body can be rotated about a back part of the body as a pivot when pressure is applied to an upper surface of the protruding part. With this configuration, the chuck pin is kept from floating when the disk rotates, and the chuck pin can be easily tilted downward when the disk is loaded.
