PROBLEM TO BE SOLVED: To provide a disk clamping device having a simple structure which effectively prevents sticking of a disk.SOLUTION: The device includes: a clamp board 2 comprising a disk abutment surface 21 which is clamped against the inner periphery of one surface of the disk when clamping the disk in cooperation with a turntable driven to be rotated; and a backplate 3 fixed to the side of the clamp board 2 opposite from the disk abutment surface 21. Through-holes 24 are drilled in the disk abutment surface 21 of the clamp board 2, and leaf springs 32 are integrally formed with the backplate 3. At the tip of each leaf spring 32, a disk-clamping a disk-pressing protrusion 33 is provided in association with the through-hole 24, and the protrusion 33 is biased by the leaf spring 32 in the direction of projecting from the through-hole 24. |
