Abstract
A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. A brake device including a brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear prevents rotation of the reel and a retracted position where the brake gear permits rotation of the reel. The reel is provided with a through hole through which a push rod extending from the brake release member projects to be brought into abutment against the drive gear of the tape drive mechanism so that the brake release member moves the brake member to the retracted position. The through hole and the push rod are in contact with each other by way of fine protrusions formed at the push rod or the through hole.
