A recording tape cartridge which enables size reduction of a drive device and is resistant to removal of a leader pin from a holding position in a case during non-use. In this cartridge, a recording tape is wound onto a single reel. The case is substantially rectangular, is formed by joining an upper case and a lower case, and rotatably accommodates the reel. The leader pin is attached to a tape end portion. A covering member opens and closes an opening for drawing out the leader pin. The opening is formed by cutting away a drive device loading side corner portion of the case. Joining portions for joining the upper and lower cases are provided at both ends of the opening. Holding portions which hold the leader pin are provided at inner faces of the upper and lower cases, on or inward of an imaginary line joining these joining portions.
