PROBLEM TO BE SOLVED: To provide a board box of a game machine for preventing illegal unsealing. SOLUTION: The board box 18 of the game machine has a set member 20 and a cover member 30. Linking parts 24 and 34, which are joined mutually in sealed condition, are provided on the set member 20 and the cover member 30 respectively. The linking parts 24 and 34 are provided on the set member 20 and the cover member 30 with unsealing parts 22 and 32 therebetween, which can be cut by using a tool, etc. Two plate-like arm parts 22a, 22b, 32a and 32b having different thickness are connected to the unsealing parts 22 and 32 with connecting parts 22c and 32c therebetween, so that the unsealing parts 22 and 32 have opening ends and are formed generally in square bracket shapes in a sectional view. The arm parts 22a and 32a having thin plate thickness are formed as weak parts so that they are deformed by an external force applied at the time of cutting. The opening end of each of the unsealing parts 22 and 32 are closed by the other unsealing part. COPYRIGHT: (C)2003,JPO
