PURPOSE: Golf putting training aids is provided to expand the control scope of difficulty with a freedom of relative position control in a hole cup and obstacles. CONSTITUTION: A golf putting training aids comprises a base plate(110), a rotating plate(120), a hole cup(129), difficulty control obstacles(127), a rotating drive unit and a support unit. The base plate has the circular opening in the travel route of a golf ball. Two or more rotation plates are equipped in the circular opening above being separated with the boundary of a concentric circle with smaller radius than the circular opening and they have the same center. The hole cup is equipped on at least one of the rotating plates and is located not in the center but the side. The difficulty control obstacles have the curved surface. The rotating drive unit applies the rotary power in order to be independently rotated. The support unit pivotally supports the rotation plate about the arbitrary fixed surface. |
