ABSTRACT:
A magnetic tape cassette utilizes a pair of reel pressure springs to stably retain the tape reels therein. The reel pressure springs have a base plate and a plurality of legs each downwardly extending from the perimeter of the base plate to be fitted into a plurality of slits provided on the tape reels, respectively. Further, each slit has a surface profile which enables the legs to resiliently depress the bottom parts of the slits, especially during the running of the tape.
