ABSTRACT:
A resilient, durable reel-locking member is provided in a magnetic tape cassette including a cassette case, a pair of reels rotatable in the cassette case to wind a magnetic tape, each of the reels including a flange and a plurality of teeth formed on a peripheral portion of the flange. The resilient, durable reel-locking member includes a slide body slidable between the reels in a front-rear direction of the cassette case, a pushing member pushing the slide body in the front-rear direction of the cassette case, a pair of cantilevered, arcuate expansions formed on opposite sides of the slide body, each of the expansions facing a respective adjacent one of the reels and extending in a direction normal to the front-rear direction of the cassette case, and a pair of claws, each of the claws projecting from a respective one of the expansions and being engagable with the teeth of the respective adjacent one of the reels. The magnetic tape cassette is having a reel-locking member with reduced susceptibility to engagement fatigue. Engagement fatigue is a frequent cause of failure and/or breakage of the reel-locking members of the conventional magnetic tape cassettes.
