A orthodontics bracket (1) has a bracket body (5), an arch wire slot (4) formed on the bracket body (5), an opening/closing lid (6) for locking an arch wire, and a opening/closing lid connecting part (7) for connecting the opening/closing lid (6) to the bracket body (5) in a slidable and rotatable state. The opening/closing lid (6) is capable of moving along a movement path that passes through a closed position (6A) at which it is engaged to the bracket body (5) in a state of blocking the arch wire slot (4), an disengagement position (6B) at which it has slid from the closed position (6A) and disengaged from the bracket body (5), and an open position (6C) at which it has rotated from the disengagement position (6B) and the arch wire slot (4) has been uncovered. The opening/closing lid (6) for locking the arch wire closes in a reliable manner and does not accidentally open, and can be readily operated so as to open or close. |
