Thus, a double bead structure is provided between the rim 10 and the spoke 20, and the connection stability of the rim 10 and the spoke 20 is further enhanced, thereby ensuring the overall structural strength of the wheel.

As shown in fig. 1 and 2, the end face of the overlapping end is adapted to the stop face 212 such that the outer surface of the overlapping end is flush with the surface of the first axial plate 233 on the side remote from the central mounting plate 22. Thus, the surfaces of the first and second bead seat structures, which form the spliced bead seat and face towards the tire, are located on the same plane, and the tire is prevented from being worn due to the fact that the surface of the spliced bead seat faces towards the tire and protrudes, so that the safety of the tire is ensured.
