を選んで構成される対応をしている。2. Description of the Related Art In a conventional tape cassette, a magnetic tape is guided along a tape running path between a head house portion in a case and a hub so that the magnetic tape can be wound or unwound on the hub. The head house is rotated by being supported on the hub fitting peripheral wall part in the shaft hole, but since this head house part incorporates various attached parts, reinforcing ribs and partition walls are erected to make it durable in strength. In other parts, the thickness of the case is increased and a durable material is selected.

カセットを提供することを目的としたものである。However, if the conventional tape cassette is made thicker or made of an impact-resistant material in order to form an impact-resistant case housing, the tape cassette becomes not only expensive but also heavy. Inconvenience in handling, and even if the hub is supported from above and below by the peripheral wall for fitting the hub, the backlash is large, the vertical movement range as a tape winding body, and the contact area with the case is the inner surface of the case. Because it is in contact with the large, frictional resistance is large, torque fluctuations are likely to occur, and it is easy for tape running to be uneven, and ribs and partition walls are concentrated on the front head house part side,
Resin tends to concentrate on the case during injection molding of the case. was there. The present invention eliminates these conventional drawbacks, enables the proper placement of the hub for winding the tape in the case housing, reduces the contact area with the case, and reduces the torque of the hub without fluctuations. The object of the present invention is to provide a tape cassette which has a good appearance, is lightweight, and is inexpensive. It is what it was.
