PURPOSE: A disk chuck is provided to allow an operator to easily fix a plurality of disks to the disk chuck and separate the disks from the disk chuck within a short period of time. CONSTITUTION: A disk chuck includes a hollow main shaft(10), a piston(20), and a clamping shaft(30). A plurality of disks(100) are stacked around the main shaft. The piston is installed inside the main shaft to be moved up and down. The clamping shaft is set in the hollow of the main shaft to be combined with the piston to be moved up and down to fix the disks or cancel fixing of the disks. A disk pushing part(32) is formed at the top of the clamping shaft, extended to the outside of the main shaft.
