Sliding resistance at a time when a locking member is moved between a locking position and an unlocking position with respect to a reel can bc lessened, and deformation of a flange welded to a hub also can be suppressed. In a recording tape cartridge 10 in which a reel 20 , at which an upper flange 24 is welded to a hub 22 , is singly and rotatably accommodated within a case 12 , a locking member 70 is configured to be able to rotate within a plane orthogonal to a rotation axis direction of the reel 20 around a position which is different from a rotational center of the reel 20 . The locking member 70 is set at a locking position, at which the locking member 70 is interposed on an extended line of the hub 22 in the rotation axis direction at a side where the upper flange 24 is welded and the locking member 70 impedes movement of the reel 20 in the rotation axis direction, and an unlocking position, at which the locking member 70 is withdrawn from the extended line of the hub 22 in the rotation axis direction at the side where the upper flange 24 is welded and the locking member 70 permits movement of the reel 20 in the rotation axis direction.
