確実な固定が難しくなるという別の問題を生じていた。The spoke wheel has a structure in which a number of spokes are stretched between a rim and a hub, and is used for an off-road motorcycle or the like, in particular, because it has good cushioning properties.
Conventionally, in such a spoke wheel, in order to extend the spoke between the rim and the hub, a special rigid flange or a protruding portion for supporting the spoke engaging portion is provided on the hub side. The spoke tip bent about 45 ° or more was locked, and the other end was pulled toward the rim by a nipple screw. (Akai Kaisho
However, specially providing a rigid flange or a protruding portion for supporting the spoke locking portion not only increases the weight but also increases the production cost. .
Further, when the spoke locking portion is largely bent as described above, stress concentrates on the bent portion, and there is a disadvantage that the strength of the spoke is reduced. Such a problem on strength could be solved by providing a so-called straight spoke with only a slight bending without providing a large bending portion as described above. Another problem was that fixation became difficult.
