    • PROBLEM TO BE SOLVED: To provide a cable bead for a tire capable of reducing the total weight of the bead by forming a circular core material by connecting a light material.
      SOLUTION: This cable bead 21 for the tire is formed by spirally winding a wire around the peripheral surface of the circular core material 22. The circular core material 22 is constituted of a pipe material 24. Both ends of the pipe material 24 are provided with protruding connection portions 24a, 24b having a small diameter shape. The outer peripheries of the connection portions 24a, 24b are respectively provided with a recessed portion 26 and a protruding portion 27. The connection portions 24a, 24b on both ends of the pipe material 24 are mutually connected through a nipple 28 including a protruding portion 28a and a recessed portion 28b which are capable of being engaged with the recessed portion 26 and the protruding portion 27. The nipple 28 is formed so as to have the outer peripheral surface almost flush with the outer peripheral surface of the circular core material 22.
