PURPOSE: A wheel structure of a robot is provided to easily fit a level of flatness of a robot without additional flatness work. CONSTITUTION: A wheel structure of a robot comprises a rotary wheel shaft(20), a tire wheel(30), a tire(40), and a rib(60). The rotary wheel shaft rotates with a power unit included inside a body unit of a small sized robot. The tire wheel is formed at the outside of the rotary wheel shaft and forms the whole shape of the wheel. The tire wraps an outer circumference of the tire wheel and is made of rubber materials to absorb impacts from the outside. The rib is protruded in the inner circumference direction of a tire in order to divide a width of the tire.
