ABSTRACT:
A three part cone member assembly is provided for positioning a flexible disk on a drive hub. The three parts are, a disk with annularly arranged apertures, a plastic trunketed cone established by oblique arms and feet which stick in the apertures thereby determining the cones geometry; the third part is a metallic member with resilient arms, positioned in the plastic cone whereby each metal spring arm urges a plastic arm against the outer surface of the respective aperture.
