Wheel and airless tire assembly

A wheel and airless tire assembly comprising:

• a cylindrical inner wheel including flanges on either edge that face each other, the flanges having fin fastening holes spaced at regular intervals around the circumference;
• a cylindrical outer wheel for receiving the inner wheel, the cylindrical outer wheel comprising a drum and a tread part molded into an axially outer surface of the drum with either a plurality of through holes or irregularities or both in such a way as to be united with the drum, with an axially inner periphery of the tread part being embedded in the through holes or irregularities;
• a cylindrical middle wheel mounted between the inner wheel and the outer wheel, that includes quadrangular elastomers with hollows inside that are arranged at regular intervals, a peripheral part with fin fastening holes that is formed on an axially inner periphery of the arranged elastomers, and ribs formed in a middle of the elastomers;
• a fixing means for firmly attaching an axially inside of the outer wheel to an axially outside of the middle wheel and then detachably uniting the middle wheel and the outer wheel;
• and
• coupling fins that allow the inner wheel and the middle wheel to be detachably held together by being inserted through the fin fastening holes of the inner wheel and the fin fastening holes of the middle wheel, after the axially inside of the middle wheel is firmly attached to an axially outside of the inner wheel.
