A ring capable of adjusting a size automatically is provided to be worn regardless of the size of a user's finger by reducing or extending the diameter of a couple of annular ring members. A ring capable of adjusting a size automatically includes a couple of semi-circular ring members(10,10a), covers(20,20a) on both sides, a decoration member(40) and a stretching spring(30). One side of the ring members is connected to a hinge(16) and mounting recesses(12) are formed on the other end of the ring members. The covers are fixed on the mounting recesses and have guide recesses(22) on the inner sides. Guide bars(44) are formed on both sides of the decoration member to be inserted into the guide recesses. A through-hole(42) is formed along the lower part of the guide bar. The stretching spring is inserted into the through-hole. |
