This disk chucking apparatus may include: a chuck bass having a plurality of holding portions, a plurality of chuck pins which are inserted in the holding portions to be elastically supported, and protrudes out from the chuck base, an elastic fragment which is arranged to be symmetrical to the chuck pin with respect to the rotation center of the chuck base, and elastically supports a disk together with the chuck pin, and wherein the elastic fragment has an inclined surface inclined with respect to a direction of equipment of the disk, and the inclined surface are increased from smaller radius than the inner radius of the disk to larger radius than the inner radius of the disk. This disk chucking apparatus make it possible to align the centers of the chuck base and disk, and to decrease the force in mounting a disk.
