Abstract: A metallic plate that is a structure of a release member, the release member being configured to be integrally rotatable with a reel accommodated in a case, and the release member moving a locking member from a locking position, at which the locking member locks rotation of the reel relative to the case, to an allowing position, at which the locking member allows rotation of the reel. The metallic plate comprises a touching surface that is to be touched by a distal end of a sliding protrusion portion that protrudes from the locking member; and a structure such that, if a plurality of the metallic plate are stacked in a plate thickness direction in a state in which the metallic plates are not attached to release members, the touching surface of each metallic plate is not in contact with any other of the metallic plates.

Abstract: A magnetic tape cartridge includes a substantially rectangular box shaped case that houses, inside a housing area, a single reel wound with a magnetic tape and equipped with a reel plate that is attracted and held by magnetic force when loaded into a drive device, and a metal-containing block that is disposed inside the case and outside the housing area of the reel, and has a proportion of metal by mass to a total mass of metal provided inside the case including the reel equipped with the magnetic tape and the reel plate of 18% or greater.
