1. A recording tape cartridge comprising:
a case rotatably accommodating a single reel on which a recording tape is wound;
a leader tape attached to an end portion of the recording tape, and disposed along a side wall of the case;
an opening for pulling-out of the leader tape, the opening being formed at a corner portion of the case, which corner portion
extends over respective portions of a front wall and the side wall of the case;
a door, whose most thin-walled portion has a thickness of 0.6 mm or greater, and which opens and closes the opening by rotating
around a supporting shaft provided at a front wall side;
an allowing portion formed in the door so that a deepest surface thereof is formed in a circular-arc shape as seen in plan
sectional view, the allowing portion allowing avoidance of contact between the door and a distal end surface of the leader
tape when the door closes the opening; and
a guide portion formed at the allowing portion, and abutting a distal end portion of the leader tape, which is further forward
than a hole portion engaged by a pull-out member of a drive device, and formed to be thick-walled in a direction of making
the distal end portion of the leader tape move away from the side wall,
wherein, when the door closes the opening, a predetermined clearance is ensured between the distal end surface of the leader
tape and the deepest surface of the allowing portion.
