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, respectively, 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, a male thread part 11d and a female thread part 12c of the nut 12 is disengaged from each other, and the male thread part 11d and the non-male thread part 11e are, respectively, inserted into a holding hole 12d and the female thread part 12c. A retaining groove 11f is retained with a stopper member 13 so that the sealing screw 11 is unremovably held in the sealing member 21. On the other hand, a head part 11b gets engaged into an engaging hole 31a. As a result, the box body 51 is linked unsealably to the box lid body 52 to seal up the board box 40.
