気テープカセツト。[Scope of Claim for Utility Model Registration] (1) A case that houses a magnetic tape, a front cover that can be opened and closed to cover the front opening of the case, and a locking member that locks the front cover when it is closed and releases it when it is opened. The locking member is composed of a rocking body pivotally supported on the inner surface of one side wall of the case, and a spring that biases the rocking body in the direction of the one side wall. In a magnetic tape cassette that is provided with a protrusion that fits into a locking recess in the front cover through a hole, one end of the spring is integrated into one corner of the oscillating body, and the spring extends along the periphery of the oscillating body, and extends along the center of the oscillating body. The spring is bent and extended in a cantilevered state, and the case is provided with a protruding stopper rib that presses the free end of the spring, and the rib is further provided with a slide prevention part to prevent the free end from slipping. Magnetic tape cassette. (2) The magnetic tape cassette according to claim 1, wherein the slide prevention portion is a protrusion.
