PURPOSE: A portable terminal accessory is provided to enable a ring to be freely rotated in a forward, backward, left, and right directions by using a ball-type first shaft capable of being rotated in various directions, thereby reducing the number of components. CONSTITUTION: A base element (10) is attached to the rear surface of a terminal. A female accommodation part (14) is formed in the shape of a hemisphere at the base element. A ring (20) is combined with the accommodation part in a freely rotatable way by using a ball-type male supporting element. The base element includes a through-hole. The through-hole is prepared next to the accommodation part and provides a path for the combining of the ring. |
