問題があつた。(Problems to be solved by the invention) As mentioned above , in the conventional spoke wheels shown in Figs. When inserted oppositely (from outside to inside) and assembled, a force acts to increase the angle of the neck of the spoke wire, and the neck of the first set of spoke wires is at the neck angle determined by JIS. The necks of the spoke lines are spread out more than 95 degrees, and the necks of the spoke lines are aligned with the left and right hub ribs, as shown in
Point contact with the spoke holes of a 2 and a 3 . Also, when the second set of spoke wires is inserted from the back side of the left and right hub ribs a 2 and a 3 toward the front surface (from inside to outside) and assembled, there is a force that tries to increase the angle of the neck of the spoke wires. As a result, the necks of the spoke wires of the second set are narrower than the neck angle of 95° determined by JIS, and the necks of the spoke wires are aligned with the left and right hub ribs a 2 , a as shown in Figure 7. Since point contact is made with the spoke hole No. 3 , each of the contact points mentioned above receives repeated loads of compressive force and tensile force due to the rotation of the wheel during actual riding of the bicycle, and stress is applied to these point contact points (neck of the spoke vehicle). There was a problem in that fatigue fractures occurred frequently, especially at the necks of the first set of spoke lines, which were widened at an angle of 95 degrees or more.
