PROBLEM TO BE SOLVED: To provide a billiard cue structure wherein a shaft is equipped with both characteristics of rigidity and elasticity, and can be easily adjusted to rigidity intended by a player. SOLUTION: This billiard cue has a shaft 10 which is connected with a bat 20 through joints 16 and 26. Then, in the shaft 10, a hollow part 12a being drilled to a length B, which is one half or longer, is provided from the joint 16 side to the distal end side while leaving one section of the distal end. In the hollow part 12a, a reinforcing member 14 comprising a bar-shape shaft core is fitted. Thus, various kinds of strength are respectively provided at the one section of the distal end of the shaft 10 and the joint 16 side of the length B, equipped with the reinforcing member 14. Also, the hollow part 12a having the length B is drilled to a location of 350 to 600 mm toward the distal end side from the joint 16 side, based on the length A of the shaft 10, which is 710 to 770 mm.
