Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a hub structure of a wheel capable of enhancing practical use and the safety of bicycle traveling so as to meet the needs in different methods of use of the wheel. SOLUTION: A ring 23 is provided between first and second frames 21 and 22 provided on a hub body 20 of a wheel, and a hole 24 is formed in the frames 21 and 22 and the ring 23. One end of a spoke 30 is inserted in the hole 24, and the other end is connected to a rim 40. The force on the spoke 30 is effectively distributed by providing the spoke 30 in the holes 24 in the ring 23 and the frames 21 and 22, and fitting a fitting part 50 to a middle portion of the spoke 30, and using the spoke 30 of different thickness.
