Abstract
A wheel provided with sub-wheels, in which a plurality of sub-wheels (31) supported rotatably about an axis extending in the same direction as that tangential to the circular rim (12) of the wheel are arranged on the circular rim to constitute a tire (40). The rotation of the tire and that of the sub-wheels are combined to cause the wheel to run in an arbitrary direction.
