Abstract
A magnetic tape cassette housing is divided into a major part and a rear frame member attached to the rear end of the major part. The major part is divided into a pair of side frame members which are formed of a material of low friction coefficient and a main body surrounded and held together by the side frame members and rear frame member. The housing is of double-layer structure consisting of inside and outside layers. The inside layers are formed with steps along the edges of the side frame members and the rear frame member, and the outside layers are so formed as to fall onto the steps and extend inwardly of the edges of the side frame members. The main body and side frame members are formed with mutually engageable, temporary fasteners. The outer surface of the outside layer is satin crape finished and at least the interface between the inside and outside layers mirror finished.
