Abstract
A structure of multiple wheel bodies integrated with an axial base to increase contact area against the ground for securing firm and smooth operation includes at least two wheel bodies and an axial base. Each wheel body is provided to and made integrated with the axial base and shares the same outer diameter. An axial hole is provided to the axial base. The outer diameter of the axial base is smaller than that of the wheel body. The axial base may have a maximal outer diameter equal to that of the wheel body. Each wheel body wears a tire made of different material. The tire is either injection molded or casting molded, or directly mounted to the wheel body.
