Abstract:
A disc gripping device is configured for gripping a disc by inserting at least three gripping members into a center hole of a disc and expanding at least one of the gripping members in a radial direction to push an inner circumferential face of the center hole. The at least three gripping members include a first gripping member having a disc contacting face for contacting the inner circumferential face of the center hole, a length of the disc contacting face being greater than a thickness of the inner circumferential face of the center hole; a second gripping member having a disc contacting face for contacting the inner circumferential face of the center hole, a length of the disc contacting face being equal to or smaller than the thickness of the inner circumferential face of the center hole, and a third gripping member having a disc contacting face for contacting the inner circumferential face of the center hole.
