When the two pushing members 1 are pressed against the front wheel of the three-wheeled vehicle, the front wheel of the three-wheeled vehicle can be positioned in the left-right direction, thereby completing the straightening of the front wheel of the three-wheeled vehicle. Alternatively, the two front wheels of the four-wheeled vehicle are driven into the positioning grooves on the outside of the two pushing members 1 in the front-to-back direction, respectively, so that the two front wheels of the four-wheeled vehicle can be positioned in the front-to-back direction and the up-down direction; then, the first power source drives the two pushing members 1 away from each other, and one of the pushing members 1 pushes one of the front wheels of the four-wheeled vehicle. When the two pushing members 1 are respectively pressed against one of the front wheels of the four-wheeled vehicle, the two front wheels of the four-wheeled vehicle can be positioned in the left-right direction, thereby completing the alignment of the front wheels of the four-wheeled vehicle. With the front wheel straightening device, when the pushing member 1 pushes the vehicle and its front wheels, the first roller 4 and the second roller 5 that support the front wheels will rotate; in this way, the resistance encountered when pushing the vehicle and its front wheels can be greatly reduced, thereby greatly reducing the load of the first power source, and further reducing the performance parameter requirements of the first power source. In addition, the first support unit 2 cooperates with the second support unit 3 to form a V-shaped positioning groove, and the front wheel of the vehicle is driven into the positioning groove, so that the front wheel can be positioned in the up-down direction and the front-back direction, which is very convenient and helps to quickly align the front wheel of the vehicle.
