ABSTRACT:
A recording tape cartridge comprises: a case which is substantially rectangular, and at which an upper case and a lower case are joined together with peripheral walls thereof abutting one another, and which rotatably accommodates a single reel on which a recording tape is wound; and an opening formed at a corner portion of the case at a side of loading the case into a drive device, the opening being for pulling out of a leader member attached to an end portion of the recording tape. Concave portions, which extend over the upper case and the lower case and which are isosceles trapezoidal in plan view, are formed at a peripheral wall of the case at the side of loading the case into the drive device. In accordance with this structure, a peripheral wall, whose end portion is a free end due to an opening being formed, can be reinforced, and thereby a deterioration in strength of the peripheral wall can be prevented.
