Claims

[Claims for Utility Model Registration] A disk-shaped magnetic disk sheet is rotatably housed in a case, and at least one of the upper and lower wall surfaces parallel to the magnetic disk sheet of the case has an opening for inserting a magnetic head. The device is provided on the case and includes an engaging portion that engages with one end of the case, and a flat plate portion that is located on a wall surface in which the magnetic head insertion opening is provided, and that slides on the case. In the magnetic disk cartridge, the flat plate portion includes a shutter made of synthetic resin that opens and closes the magnetic head insertion opening, wherein the engaging portion extends from an edge of the flat plate portion to the upper and lower wall surfaces in a direction perpendicular to the flat plate portion. a first wall extending by a length shorter than the distance between the two, a first wall extending in a direction perpendicular to the first wall from an edge of the first wall opposite to the flat plate, and facing the flat plate; a second wall, and a protrusion planted on an edge of the second wall opposite to the first wall so as to face the flat plate; A magnetic disk cartridge characterized in that a protrusion extending in the moving direction and capable of engaging with the protrusion is formed.
