Claims

[Scope of utility model registration request]

The upper half and the lower half form a cassette body that stores magnetic tape, and a pivot shaft for a front cover that covers the front of the cassette body so that it can be opened and closed is attached to a mounting recess formed in the side wall of the upper half. In a magnetic tape cassette in which the fixed end of a spring for keeping the front cover in a closed state is locked to the pivot shaft and the free end is pressed against the inner surface of the upper half, the front cover is rotated to the closed position. A magnetic tape cassette characterized in that a stopper protrusion is formed on the inner surface of the upper half, the stopper protrusion coming into contact with the tip of the free end of the spring and pressing the pivot shaft into the mounting recess.
