A storage case for a cassette such as video tape cassette includes a base having a bottom, a rear wall and a pair of side walls, and a cover pivotably mounted on the base and having a top, a front wall and a pair of side walls. The cover is angularly movable with respect to the base between open and closed positions. A cylindrical projection is mounted on the bottom and located more closely to one of the side walls of the base than to the other for being inserted into a hole in a supply reel of the cassette when the latter is placed in the storage case. The cylindrical projection has a plurality of locking fins which can be fitted in grooves in an inner wall defining the hole in the supply reel of the cassette. Accordingly, the supply reel is locked by the cylindrical projection and its locking fins against accidental rotation and hence loosening of a magnetic tape wound around the supply tape. The other side wall of the base has a pair of tapered vertical ridges which serve as a takeup reel stopper when they mesh with teeth defined on a flange of a takeup reel of the cassette.
