ABSTRACT:
A magnetic tape cassette having an upper part and a lower part combined during assembly to form a unitary housing, a front lid that can be moved between an open position and a closed position, a pair of reel hubs rotatably mounted within the cassette housing for winding a tape thereon, and a hub lock member for locking the pair of reel hubs, includes a structure to temporarily secure the hub lock member to the upper part in a range outside a normal movable range of the hub lock member. This structure is formed as a cut-away portion having a predetermined width in its movable direction formed on the hub lock member and a stopper portion formed on the lower part in association with the cut-away portion, so that an edge of the cut-away portion comes in contact with the stopper portion to prevent the hub lock member from being once again secured to the upper part once the housing is assembled.
