摘要： A magnetic tape cassette has a slidable braking member for controlling the rotation of reel hubs about which a magnetic tape is wound. In order to facilitate the process of assembling the magnetic tape cassette, the braking member is temporarily secured to an upper part of the cassette housing with a light pressure at a position outside its normal slidable range. After the completion of the assembly, the braking member is disengaged from the upper part of the cassette housing, and thereafter it moves only within its normal slidable range in order to lock or release the reel hubs.
