ことを特徴とするデイスクチヤツク装置。 A plurality of arc-shaped actuating parts that can be expanded and contracted in the radial direction are connected to the tip of the spindle, and each actuating part has a receiving part that comes into contact with the inner circumferential side surface of the disk, and an inner part that comes into contact with and separates from the inner circumferential surface. A push shaft having a wedge member at its tip is disposed opposite to a disk support portion having a circumferential surface support portion, and the push shaft is separated from the disk support portion and the disk is inserted into the disk support portion. and a chuck state in which the disk supporting portion is expanded in diameter by the wedge member and the inner circumferential surface supporting portion is in contact with the inner circumferential surface of the disk,
Further, the pushing shaft includes an elastic member that comes into contact with the other inner side surface of the disk and clamps both inner side surfaces of the disk between the receiving part and the push shaft when the push shaft is displaced to the chuck state. What is claimed is: 1. A disk chuck device characterized by having a structure in which
