ABSTRACT:
The present invention is related to a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit, formed by abutting and combining upper and lower shells and in which the inner shell is run in rotation to cause the shutter members to open or close an aperture provided in the main cartridge body unit. The inner shell is formed by a resin molding portion comprised of a first molded portion for forming the inner shell and a second molded portion connected to the first molded portion. The second molded portion is provided at a position forming the aperture in the inner shell and is connected to the first molded portion through a flanged thin-walled section. The inner shell is formed by severing the second molded portion and the flanged thin-walled section.
