The base panel is provided with a first section which carries a pressure spring adapted to depress the tape reels toward the lower cassette casing, and a second section surrounding the first section, the second section having a thickness less than that of the first section. Each of the peripheral walls includes a plurality of reinforcement ribs which inwardly protrude therefrom, and is of a substantially same thickness with respect to each other and as that of the second section of the base panel. The thickness of the second section of the base panel and the peripheral walls is as thin as 50 percent of that of the first section.
