Abstract
A recording tape cartridge is provided that prevents damage to a recording tape if it experiences a shock. The recording tape cartridge includes a reel on which a recording tape T is wound, an upper case and a lower case that form the case thereof, a reel accommodated between the upper case and lower case, and a compression coil spring that urges the reel against the lower case. An allowable lower limit value of the distance between the reel and the upper case is defined by the spring axial-direction length of the compression coil spring when it is most compressed.
