Claims

[Scope of utility model registration request]

A mounting recess with an opening on the lower half side is provided in the front side wall of the upper half that forms the cassette main body together with the lower half, and a rotation support shaft of the front cover that is mounted in the mounting recess so as to be openable and closable at the front of the cassette main body is provided in the mounting recess. In a magnetic tape cassette which is pivotally supported, a locking protrusion that engages with the pivot shaft and prevents the front cover from falling off, which is temporarily fixed to the upper half of the cassette body before assembly, is provided on the opening side of the mounting recess. A magnetic tape cassette characterized by a protruding part.
