The present invention discloses a wheel structure and a kayak using the same, relating to the field of ships. The wheel structure mainly comprises wheel bodies, a shaft and a support rod, wherein the connecting piece is arranged at one end of the support rod opposite to the wheel body, a bidirectional ratchet wheel mechanism is arranged between the shaft and the support rod, the bidirectional ratchet wheel mechanism can selectively control the shaft through adjustment, to make same rotate only in one direction, and then achieve the purpose of controlling the rotation direction of the wheels; the wheel structure is mounted on the kayak, when being loaded, the kayak is effortlessly pushed under the action of wheels, and the rotation direction of the wheels is limited by the bidirectional ratchet mechanism so that the wheels can only roll towards the vehicle, therefore, the pushing person does not need to powerfully offset the retreating force of the wheels, that is, it is easier and effortless to push the kayak to be loaded.
