PROBLEM TO BE SOLVED: To make it easy to swing in using a golf practice instrument, thereby the lift dimension of the rail body from the floor at the position of the ball resting on the floor is held low, and the gap between the rail body and the resting ball is kept large, in case of the head is pulled backward along the circle arc orbit. SOLUTION: In the golf practice instrument composed in such a manner that the rail body 1 consisting of two rail materials 1a is attached to a putter 160, that a ball 2 hit between the tow rail materials returns to the head 161 along the rail body, the attachment means to attach the rail body 1 to the putter 160 and the rail body 1 are connected through tilting member materials 13 and 13a. Said tilting member materials are composed in such a manner that tilting motion is possible in the top and bottom direction for the attachment means. And the rail body 1 is also composed in such a manner that tilting motion is possible in the top and bottom direction for the tilting member materials 13 and 13a.
