Golf club with attached training wheel

A golf swing training device, comprising:

• a golf club composed of a shaft, handle, and clubhead;
• oriented, with respect to a relatively flat and level playing surface, in an address position commensurate with the designed loft and lie angles intended by the clubhead manufacturer, the clubface aimed in a square alignment with respect to a target line on said playing surface, having
• a free-spinning wheel or roller assembly, having a suitably stiff and lightweight construction or a rim-and-spokes type construction, including a radial bearing, either permanently mounted to, or integral with, or having means for releasably securing and aligning said wheel or roller assembly to the golf club shaft or hosel so that it may be attached and detached from a previously constructed golf club without the necessity of extracting the shaft from the hosel, with
• the diameter of the wheel or roller and the vertical location and alignment of the said mounting with respect to the golf club being so predetermined that the axis of rotation of the wheel or roller assembly is perpendicular to the target line and parallel to the playing surface, and that when the clubface of the golf club is at said address position, the perimeter of the wheel or roller will be in substantial, tangential contact with the playing surface.
