A wheel structure and a canoe using the wheel structure, which is related to the field of sailing vessels. A body of the wheel structure consists of wheels (1), a shaft (2), and a support rod (3). A connecting element (4) is provided at ends of the support rod (3) opposite the wheels (1). A two-way ratchet mechanism (210) is provided between the shaft (2) and the support rod (3). The two-way ratchet mechanism (210) is capable of selectively controlling the shaft (2) by means of adjustment, and allowing same to rotate in one direction, thus achieving the goal of controlling the direction of rotation of the wheels. The wheel structure is mounted on a canoe, when same is mounted to a vehicle, the canoe is easy to push under the effect of the wheels, at the same time, the direction of rotation of the wheels can be limited by means of the two-way ratchet mechanism (210), so that the wheels can only rotate in the direction of the vehicle, as such, the need for a person pushing to cancel the force of the wheels going backwards is obviated, that is, the canoe can be pushed easily and effortlessly to be mounted on the vehicle.
