<p>PROBLEM TO BE SOLVED: To attain assembling and disassembling safely with simple configuration by providing a shaft part with an arrangement part and arranging a long- sized member for rotating the shaft part in the arrangement part in a gate ball stick consisting of the disassemblable shaft part and a heat part. SOLUTION: In the gate ball stick to be used in a gate ball, the shaft parts 4 and 5 and the head part 6 are screwed by joints 2 and 3 and a hole part 9 is disposed in the neighborhood of the screw 8 of the shaft part 5. When the gate ball stick 1 is disassembled, the head part 6 and the shaft part 5 are disassembled at the part of the joint 3 and, then, the shaft parts 4, 5 are disassembled at the part of joint 3, the long-sized member 10 is fitted to the hole part 9 of the shaft part 5 at this time. When the long-sized member 10 is rotated in the direction of a arrow A while holding the shaft part 4, the shaft part 5 can be rotated in the direction of the arrow B by a small amount of force by the principle of a lever and, then, easily disassembled.</p> |
