A wheel structure includes a variable spoke configured to connect a wheel and a central shaft and having a length that varies in a radial direction of the wheel, a spoke driving unit configured to provide power for changing the length of the variable spoke in the radial direction, and a power transmission unit configured to transmit power from the spoke driving unit to the variable spoke. A plurality of variable spokes are spaced apart from one another in the circumferential direction. The power transmission unit includes an output shaft configured to rotate by receiving power from the spoke driving unit, and a clutch configured to connect the variable spoke and the output shaft and selectively transmit a rotational force of the output shaft to the variable spoke or cut off the transmission of the rotational force to the variable spoke.
