Abstract
A recording tape cartridge which includes a case, a reel including a hub accommodated in the case, a locking member supported to be non-rotatable relative to the case and disposed within the hub, and a switching member disposed in the case. The hub is provided with an engaging portion therein. The locking member can attain a rotation-locking position, at which the locking member engages with the engaging portion and fills a gap between the reel and the case in an axial direction of the reel, and a rotation-enabling position, at which the state of engagement with the engaging portion is released and the locking member being withdrawn from the gap. The switching member retains the locking member at the rotation-locking position at times of non-use of the recording tape, and moves the locking member to the rotation-enabling position when operated in a predetermined direction by a drive device.
