ABSTRACT:
A recording tape cartridge includes: a case accommodating a reel on which a recording tape is wound; a brake member provided non-rotatably with respect to the case; a lock member provided in a mounting portion on the inner surface of a top plate of the case to be slidable in a radial direction of the reel; and a falling-out preventing member for keeping the lock member from being removed from the mounting portion. The brake member is arranged to selectively assume a rotation locking position where the brake member is engaged with the reel to prevent the reel from being rotated and a rotation permitting position where the brake member is disengaged from the reel to permit the reel to be rotated. The lock member is arranged, when the brake member assumes the rotation locking position, to be interposed between the upper surface of the reel and a top plate of the case, thereby preventing the reel from being moved axially thereof. The lock member is also arranged, when the brake member is moved from the rotation locking position to the rotation permitting position, to be removed from between the upper surface of the reel and the top plate of the case in response to the movement of the brake member, thereby permitting the reel to be moved axially thereof. When the brake member assumes the rotation locking position, a clearance is defined between the lock member and the brake member, and the clearance is made smaller than the movement stroke of the brake member from the rotation locking position to the rotation permitting position.
