PURPOSE:To provide a wheel which needs not a tire and does not have flat tire and which prevents vibration by constituting the whole wheel from an inner ring to an outer ring out of plastic, and giving spring characteristics to a part of the outer ring. CONSTITUTION:A wheel is formed by integratedly-molding from an inner ring 6b to an outer ring 8b with plastic. At the same time, a honeycomb structure part 16, which is conventionally equivalent to a spoke part, slit holes 17, and a part 18 with spring function are provided between the inner ring 6b and the outer ring 8b. Besides, the slit holes 17 near the outer ring 8b are bent so as to function as a spring, if right-angle or the other direction force is applied. Namely, the width of the spring functioning part 18 of the honeycomb 16 and the outer ring 8b is made small by providing the slit, holes 17, and the connecting length is made long by forming in wave. It is thus possible to make the spring functioning part have an appropriate spring function, and soften vibration and shock caused in the outer ring 18 by the spring functioning part 18. Thus, it is possible to provide comfortable driving.
