By optimizing the structure of the spoke 20, the contact surface area of the spoke 20 and the rim 10 is increased, and the welding stability between the spoke 20 and the rim 10 is ensured.

Specifically, since the bent flange 211 is formed by bending at least a part of the edge of the vent hole 21 toward the inner side of the rim 10 in the axial direction, the bent flange 211 can effectively increase the area of the contact surface of the spoke 20 with the rim 10 in the axial direction of the rim 10, so that after at least a part of the bent flange 211 is bonded to the inner wall surface of the rim 10 and welded to the rim 10, the first bead structure 100 is formed at the joint of the two, the first bead structure 100 has not only a sufficient length in the circumferential direction of the rim 10 but also a sufficient width in the axial direction of the rim 10, that is, the first bead structure 100 can effectively increase the welding area between the spoke 20 and the rim 10, thereby ensuring the welding stability between the spoke 20 and the rim 10 and further improving the connection reliability between the two, and thus ensuring that the vehicle does not obstruct normal running of the vehicle due to the occurrence of cracks between the spoke and the rim of the wheel during running of the vehicle, the occurrence of traffic accidents is avoided, the life safety of users is guaranteed, and the practicability of the wheel is improved.

In the present application, in order to ensure the aesthetic appearance of the entire wheel, as shown in fig. 1, the periphery of the vent hole 21 is bent toward the inside in the axial direction of the rim 10 to form a bent flange 211 having an annular shape, and a part of the bent flange 211 is a welded flange section 2111 which is attached to the inner wall surface of the rim 10 and is welded to the rim 10.
