ABSTRACT:
An improved adjustable wheel structure mainly adapted for use in a trailing vehicle on which a yacht, boat or motorcycle can be mounted for transportation; the present wheel structure is provided with a special nut member having its inner surface half threaded and half smoothed, and the nut member is able to be adjusted forward or backward so that the threaded inner surface thereof can be selectively engaged with a vertically disposed adjusting screw rod which has a smaller diameter than the central through hole of the slidable nut member so that the wheel structure can be smoothly adjusted in height; as the threaded side of the nut member is adjusted to disengage from the screw rod with the smoothed side thereof in contact with the adjusting screw rod, the wheel structure can be adjusted quickly rather than in stepwise manner.
