Abstract

A U-shaped slide guard is slidably mounted on the bottom of a lower half case of a magnetic tape cassette. The slide guard has a flat bottom wall which lies flush with the bottom wall of the lower half case. A cantilever type locking member integral with the lower half case bottom wall has an end part projecting downwardly from the bottom of the lower half case. The slide guard has aligned locking holes for selectively receiving the end part of the locking member so that the position of the slide guard is maintained by engagement of the end part of the locking member with a given one of the locking holes. A tapered ramp formed on the rear edge of the slide guard is aligned with the locking holes and the ramp extends rearwardly and downwardly. When the slide guard is attached to the lower half case, the end part of the locking member slides on the tapered ramp for cammed projection into the bottom of the lower half case so as to easily ride on the upper surface of the bottom wall of the slide guard until reaching a given one of the locking holes.
