ABSTRACT:
A disk cartridge for accommodating a disk is composed of upper and lower shells. The upper shell has a pair of right and left wings covering right and left incorrect-insertion detection cut-away portion. When the right and left wings are formed in an integral fashion on the upper shell by means of molding, the upper surfaces of the respective wings in the regions inside periphery ribs are recessed so that these regions have a thickness nearly equal to the thickness of the roof wall of the upper shell. This structure allow the wings to have a great mechanical strength without having deficiency of synthesis resin.
