PROBLEM TO BE SOLVED: To provide a nail inclination angle-measuring gauge in a pachinko machine, by which gauge the inclination angle of nails planted on a game board surface is easily and rapidly measured and also a measuring work is efficiently executed. SOLUTION: Each of nail inclination angle measuring gauges G1-G7 has a measuring part 1 for measuring the inclination angle of each nail planted on the game board surface. The measuring part 1 is formed to be a flat plate shape, both side edges 5 and 6 of the part 1 to be put along the nail are inclined by a prescribed angle with respect to a tip edge 4 which is abutted on the game board surface, notch parts 3 where the head of the nail faces are arranged at the terminal ends of both side edges 5 and 6 of the part 1 which are inclined, miniaturization is attained, measurements are facilitated, a plurality of gauges G1-G7 are pivotally arranged to be freely rotatably fed thus enhancing the efficiency in the work.
