A magnetic recording tape cassette comprises a pair of hubs around which a magnetic recording tape is wound and which are accommodated in a casing. The casing is provided with an access opening through which the magnetic recording tape is drawn out for recording or reproduction and a lid member supported for rotation between a closed position in which it closes the access opening and an open position in which it opens the same by way of a pair of pivots which are formed on opposite ends of the lid member and are rotatably received in respective holes formed in the walls of the casing perpendicular to the access opening. At least one of the pivots is provided with a slit extending along the longitudinal axis thereof. The hole or holes for receiving the pivot provided with the slit are arranged to support the pivot at three points. |
