Claims

[Scope of utility model registration request]

A disk 2 is rotatably housed in a disk case 1, and the disk 2 is integrated with a disk-shaped seat 9 and a plastic knob 1 that is integrally connected to the center of the sheet 9 and faces the drive shaft insertion window 3 of the disk case 1. 10, which has a spindle insertion hole 14 in the center of the hub 10 into which the disk drive side spindle 19 is inserted, two slits 48.48G diameter on the inner peripheral surface of the spindle insertion hole 14. Two points P with respect to the support shaft 19 are provided in the peripheral wall portion 31 of the support shaft insertion hole 14, which is provided in the direction and partitioned by the slits 48 and 48.
1. A disk cartridge characterized in that a circumscribed surface 32.32 that contacts at P2 is formed, and the bipolar contact surface 32.32 is symmetrical with respect to an axis of symmetry passing through the hub center P.
