PROBLEM TO BE SOLVED: To provide a practicing device for stroking without displacement of the center of a putter head from an extension line connecting a target point and a ball. SOLUTION: The putting practice device includes a rear leg 2 which constitutes an isosceles triangle including two long-length rear legs 2a and 2b as equilaterals, an apex 2ab-1 formed by connecting one ends of the rear legs 2a and 2b to each other, and the other ends of the rear legs 2a and 2b as bottom side ends 2a-1 and 2b-1. A support bar 1 and long-length side legs 3a and 3b are connected respectively to the apex 2ab-1 and the bottom side ends 2a-1 and 2b-1 of the rear leg 2 parallel to one another in the direction perpendicular to a surface of the isosceles triangle formed by the rear leg.
