とができる。In the wheel according to the present invention assembled as described above, the flange 11 of the drum 10 constituting the wheel is bent 14 inwardly to approach the center line of the wheel. It is possible to reduce the bending moment applied to the joint between the drum 10 and the flange 11, thereby making it possible to provide sufficient strength to the flange 11, and in particular, there is no need for conventional reinforcement members. Therefore, reduction in wheel weight can be achieved reliably.

こととなる。Furthermore, since it is not necessary to weld reinforcement to the flange 11 of the drum 10 from the side, there is no thermal influence on the inner diameter of the drum 10 (thereby, the same accuracy of the inner diameter of the drum 10 can be achieved. If the shoulder portion 16 of the drum 10 is bent to have the minimum radius of curvature that can be processed as described above, the shoulder portion 16 will have the strength to withstand the stress relatively concentrated on the shoulder portion 16 due to this curvature. 16, it is possible to minimize thermal effects such as thermal distortion on the drum 10 due to the welding between the drum 10 and the spoke plate 5, and in addition to the above, it is possible to improve the accuracy of the drum 10. This will contribute to
