A magnetic tape cassette storing case includes a cover member, and a casing member which is pivotally coupled to the cover member. Rotation preventing protrusions are so positioned that they are engaged with the hubs of a magnetic tape cassette whether the cassette is inserted in a first predetermined direction or in a second predetermined direction which is opposite to the first predetermined direction. Two pair of recesses for receiving the thicker portion of the cassette are formed in each of the major walls of the cover member and the casing member which, when the cassette is put in the storing case, cover the upper and lower surfaces of the cassette, in such a manner as to permit insertion of the cassette not only in the first predetermined direction but also in the second predetermined direction.
