    • The present invention relates to a magnetic tape cassette comprising upper and lower halves of cassette forming the cassette body wherein supply and take-up reels for a tape are to be loaded, a front cover that swivels and covers rotatably the front side of the cassette where the tape runs and a front cover spring that keeps causing the front cover to be swiveled in one direction.In the upper half of cassette offered by the invention, the side wall of the upper half of cassette is provided with a loading opening, and when a shaft provided on the front cover for supporting the front cover when it swivels or rotates is positioned at the corner of the loading opening, it is possible to mount the front cover regularly and finally only on the upper half of cassette owing to a stopper protrusion that checks the downward movement of the shaft provided on the front cover and a slip-prevention protrusion that checks the forward movement of the same shaft.
