摘要:
A pad which is to be provided in the interior of a videotape cassette according to this invention is in the form of a hollow cylinder. When fitted in place in the interior of a videotape cassette, the cylindrical pad is yieldingly deformed to produce a resilient force, thereby pushing a videotape against an associated guide stud. Because of the cylindrical shape, the pad requires no large space to mount, and accordingly a videotape cassette can be substantially reduced in size. The cylindrical pad need only be pushed into place in the interior of a cassette housing, and this easy mounting is advantageous to the mass-production of videotape cassettes.
