<p>A magnetic tape cassette includes a cassette casing (1) comprising upper and lower cassette parts (2, 3) joined to each other, a pair of reel hubs (7, 8) rotatably disposed in the cassette casing (1) and supported by the cassette parts (2, 3), and a magnetic tape (T) wound around the reel hubs (7, 8) and housed in the cassette casing (1). The cassette parts (2, 3) each have a pair of aligned apertures (2a, 2b, 3a, 3b) defined therein for receiving hub drive shafts, and a pair of circular recesses (2a1, 2b1, 3a1, 3b1) defined in inner surfaces of the cassette parts (2, 3) in coaxial surrounding relation to the apertures. The reel hubs (7, 8) have axial apertures for receiving the hub drive shafts and open ends loosely fitted in the recesses (2a1, 2b1, 3a1, 3b1). <IMAGE></p> |
