PROBLEM TO BE SOLVED: To provide a game machine which can prevent unfair acts to open a board storage box and to secretly replace the box with a duplicate copy. SOLUTION: The game machine is equipped with an attaching part (attaching base 150') to attach a board storage box 220 to the game machine 200. Attaching work to attach the attaching part 150' to the board storage box 220 and assembling work to assemble a lid body 204 and a base body 203 by a fastening means (a one-way screw 160, attaching projections 205a-205c, attaching piece parts 156a-156c) are simultaneously carried out into an irreversibly fixed condition. Thus, unfair acts to open the board storage box 220 and to secretly replace the box with the duplicate copy can be prevented. Since the fastened part can be cut down to the requisite minimum by this constitution, cost can be reduced and assembling work for the board storage box 220 is facilitated.
