  • the plates for checking address are to allow both eyes to be accurately placed right above a ball and a putting line in golf putting. Furthermore, as a mirror for checking accuracy of a stance or swing in golf, a mirror for checking alignment is known, which has a mirror member having predetermined vertical and horizontal sizes, a few linear lines for checking alignment that are drawn on the mirror member, a scale drawn on the mirror member to allow checking of positions of each part of the body, a swing width, or the like, and a tee peg insertion hole for checking the trajectory of a ball that is drilled in the mirror member to practice golf putting (Patent Document 2). In the invention of Patent Document 2, an improvement is made to the invention of Patent Document 1, and the plates of Patent Document 1 are replaced with a mirror to allow players see themselves reflected in the mirror and allow more effective practice.
