部４ａが固定されているにも拘わらず前述した係合角度
がずれてしまうおそれがあるといった問題点である。That is, in the wheel device I described above, since the receiving surface 7 and the engaging surface 8 that engage the spokes 4 and the hub 2 are conical, the contact between the two surfaces 7.8 causes a large amount of damage. The diameter portion 4a and the hub 2 are fixed, which uniquely determines the engagement angle between the spokes 4 and the hub 2. However, when a large number of spokes 4 are tensioned, variations in the tightness occur between the spokes 4. Furthermore, due to variations in the machining accuracy of the receiving surface 7 and the engaging surface 8, there is a risk that the aforementioned engaging angle may deviate even though the large diameter portion 4a is fixed. This is a problem.
