发明名称 Practice device for corrected golf swing
摘要 A practice device for corrected golf swing basically comprises a frame which is relatively long in one direction and a pair of strip-shaped members extending in alignment with each other in the one direction so as to define a straight target line. The frame includes a pair of space defining members extending in the one direction in parallel to each other leaving a space therebetween so that said space is adjustable. The strip-shaped members linearly extend outward in the one direction from respective middle locations on the lines connecting respective pairs of the frame ends which are opposed in a direction orthogonal to said one direction, respectively.
