Done .

이와 같은 제 1 허브(10)의 구성에 의해, 도 6에 도시된 것처럼, 먼저, 조임링(20)을 샤프트(S1)에 끼운 상태에서, 샤프트(S1)의 선단을 축구멍(15)에 끼우고, 조임링(20)을 샤프트(S1)의 선단쪽으로 이동하여, 슬리브(13)에 조임링(20)을 끼운다. 이후, 볼트(17)를 원통형 바디(12)의 볼트구멍(16)을 통해 조임링(20)의 체결구멍(22)에 체결하면, 조임링(20)이 원통형 바디(12) 쪽으로 이동하게 되면서, 조임링(20)에 의해 슬리브(13)의 직경이 수축되고, 슬리브(13)가 샤프트(S1)의 선단을 그립하게 된다.With such a configuration of the first hub 10, as shown in FIG. 6, first, the tip of the shaft S1 is inserted into the shaft hole 15 while the tightening ring 20 is inserted into the shaft S1. Insert the tightening ring 20 to the front end of the shaft (S1), and fits the tightening ring 20 to the sleeve (13). Thereafter, when the bolt 17 is fastened to the fastening hole 22 of the tightening ring 20 through the bolt hole 16 of the cylindrical body 12, the tightening ring 20 moves toward the cylindrical body 12. The diameter of the sleeve 13 is contracted by the tightening ring 20, and the sleeve 13 grips the tip of the shaft S1.

Thus, when the first hub 10 rotates, the air resistance generated by the hole can be eliminated, and the balance problem caused by the air resistance can be solved, and the rpm of the shaft can be increased.

도 4를 다시 참조하면, 상기 결합리브(11)는 외측단(112)의 폭(W2)이 내측단(111)의 폭(W1) 보다 크고, 내측단(111)과 외측단(112)을 연결하는 측면(113)이 오목한 곡선 형태로 형성된다.
