Golf putting trainer

Abstract

Provided is a putting-training tool for enabling a user to train the putting while realizing that the error of a ball hitting angle may be confined within about 2 degrees. The putting-training tool is characterized in that a golf ball rolling groove has a width of 9 mm to 5 mm and has a transverse section gently-recessed into a curved face for supporting a golf ball at one point, so that the golf ball may not leave, in case a putting force to roll the golf ball by about 1.5 m to 2 m on the green is applied, the golf ball rolling groove for errors of the ball hitting angle less than 2 degrees.
