ABSTRACT:
An improved wheel lock for a video tape cassette is molded as one whole unit (part) of a flexible and elastic plastic material. This single part can effectively prevent the wheels of the tape cassette from free rotation or make it rotate freely, which is conventionally effected by the interaction of five units (parts). This single unit is easy to manufacture, low in its cost and accurate in its action.
