PURPOSE:To secure such a wheel as being different in design and form inexpensively, by forming a hub and a wheel main body into each separate body, while clamping them as one body with a clamping device, in case of a built-up wheel suitable for a two-wheeled vehicle. CONSTITUTION:This built-up wheel consists of a hub H, a wheel main body W assembled detachably to this hub H and a tire T attached to the main body W. And, the hub H and the wheel main body W are coupled by a clamping device C composed of a stack bolt 9 and a nut 10. The hub H consists of a hollow cylindrical bearing cylinder part 1 and a wheel support part 2 solidly extended in a radial direction from the axial one side. As for the wheel main body, it is made of hard synthetic resin and consists of a boss 15, a spider 16 extending in a radial direction solidly with this boss 15 and a rim 17 being solidly formed on the circumference. In addition, the boss 15 is made up of providing for a cylindrical part 15a to be fitted in the circumference of the bearing cylinder part 1. |
