PROBLEM TO BE SOLVED: To provide a hinge for fitting a transom capable of freely fitting the curved transom to a curved game machine installation island board regardless of its curvature of radius. SOLUTION: When the curved transom 52b is to be fitted to a curved girder 51b, the first pins 12 of two transom fitting hinges are adjusted to be located on a straight line, and wood screws 11b are inserted into three screw holes 11a of each fitting plate 11 to fix the fitting plate 11 to the upper face of the girder 51b, then the positional relation between the girder 51b and the transom 52b is adjusted. After the positional relation between the girder 51b and the transom 52b is determined, support plates 15 are rotated so that the screw holes 15a of the support plates 15 are located nearly at the center in the thickness direction of the transom 52b. Wood screws 15b are inserted into the screw holes 15a of the support plates 15 to fix the support plates 15 to the upper face of the transom 52b, and finally the support plates 15 are fixed to rotary plates 13 by fastening securing nuts 16, thus prohibiting the rotation of the support plates 15.
