A two-piece reel structure for taking up an elongated tape, such as a magnetic tape, a film and the like, is provided. The reel includes two similar halves, each of which includes a frustum-shaped central shaft portions. A bottom plane of each frustum is provided with a plurality of engaging means and receiving holes. Each of the engaging means includes a hook portion adapted to engage with a flat projection in the receiving hole on another half reel and a tongue portion located at one end of the hook portion and adapted to press a free end against an edge of the receiving hole opposite to the flat projection to prevent the hook portion from disengaging from the flat projection. By engaging the engaging means on a first half reel with the receiving holes on a second half reel and then turning the two half reels in opposite directions, the two half reels can be easily and firmly connected to each other to provide a complete reel.
