PROBLEM TO BE SOLVED: To provide a board box sealing device for a game machine which prevents a dishonest act of altering contents of a game from being committed by securely sealing a board box of the game machine and enabling an early discovery of the dishonest act when the act is actually done. SOLUTION: Unit members 20 and 30 are secured on a box body 41 and a box lid body 42, and the box body 41 is covered with the box lid body 42. Then, when a sealing screw 11 is screw-threaded completely into a nut 12, the sealing screw 11 is unremovably held in a sealing member 21 and its head part 11b is engaged into an engaging hole 31a. As a result, the box body 41 is connected unsealably to the box lid body 42 to seal up the board box 40. The board box 40 is unsealed by cutting rib members 36, 36 neighboring both side parts of the connecting member 33 using nippers, etc and then the connecting member 33 is cut.
