PROBLEM TO BE SOLVED: To improve a production efficiency of a game board while performing a measurement work for nails driven into the game board through adjustment of their attitudes against the game board. SOLUTION: Right and left measuring units 22 measure a distance between a center line L1 and each of the nails as the right and left movable bases 24 move toward a spaced-apart direction from each other by a force capable of bending a pair of nails 12 after the nail contact units 31 of the right and left adjuster elements 27 are inserted into a nail space of the pair of nails 12 driven into the game board 11. When the measured distance coincides with a reference distance set from the center line L1, the pair of nails 12 are inclined outwardly from their root portions driven into the game board 11 by the right and left adjuster elements 27 and then the nail spaces at the pair of nails 12 are adjusted to the reference nail space.
