Abstract
A cassette case which allows positioning and fixing of a hub without biting of a hub pawl, and enhances the convenience with which the case is used. A plate-like portion comes at its edge into contact with a corner of a peak of a hub pawl without the plate-like portions of the projection coming at their edges into engagement with the hub pawl when a cover section of a storage case has been closed relative to a casing section. The sum of pushing forces exerted on the hub pawl by the plate-like portion causes the hub to rotate to thereby introduce the hub pawl into a space formed between the plate-like portions. In order to carry out the above-mentioned operation, the plate-like portion is designed to have an edge extending in a direction from a front to a rear, and vice versa, of a magnetic tape cassette to be encased in the storage case, and the plate-like portion is designed to have an edge making a predetermined angle with the above-mentioned direction.
