<p>A video tape cassette in which no screws are used has, at each corner of the lower half member of the cassette, an upstanding pole 4, the pole being integrally formed with the lower half member 1, and being provided with a shoulder 2 and an upstanding protrusion 3. The corresponding positions of the upper half member 5 are provided with pole-receiving portions 9, each being integrally formed with the upper half member, and being provided with a pole-receiving hole 6, a deformation hole 7 and a through hole 8. When assembling the cassette, the upstanding protrusion is inserted through the through hole into the deformation hole, is deformed into a round head 3' by means of an acoustic horn, whereby making the cassette undisassemblable. The device of the present invention thus constituted brings light weight and low manufacturing cost, as well as preventing possible damage to the tape which can occur when the cassette is disassembled. <IMAGE></p> |
