An adapter in the form of a hemispherical body of a diameter greater than that of the center opening of the disc is mounted on the spindle in such a manner that the center of a spherical body from which the hemispherical body of the adapter is severed coincides with the center axis of the spindle at all times. The adapter is urged by a spring to be biased with the center thereof serving as the center of rotation.
