Claims

[Claims for Utility Model Registration] A horizontal annular flange is integrally provided on the upper part of the outer periphery of a horizontal metal central disk having a center hole and an eccentric hole through a vertical cylindrical part, and a sheet is attached to the flange. A shaped recording medium is fixed horizontally, and a small-diameter ring and a large-diameter ring are integrally outsert-molded with synthetic resin on the outer periphery of the center hole on the upper surface of the center disk, and on the outer periphery of the cylindrical part on the lower surface of the flange. In a disk cartridge in which a central disk and a sheet-like recording medium are rotatably housed in a cartridge consisting of upper and lower halves, the small-diameter ring and the large-diameter ring are combined through a plurality of through holes provided in the cylindrical portion. A disk cartridge characterized by being connected by a resin connection part.
