スクカセット。A cassette housing consisting of upper and lower halves that accommodates a flexible magnetic disk, and a shutter slidably attached to the cassette housing to open and close a head insertion hole formed in the cassette housing, The shutter is biased to a position where it closes the head insertion hole by a V-shaped torsion coil spring consisting of a winding part and straight parts at both ends, and one end of the straight part of the torsion coil spring is connected to the upper and lower halves. A fitting portion is provided that elastically fits into a support shaft portion formed on one side, and the end of the other straight portion of the torsion coil spring is locked by the restoring force of the spring in a locking portion formed on the shutter. A magnetic disk cassette characterized by:
