PROBLEM TO BE SOLVED: To provide a game machine capable of preventing the act of fraudulently changing the contents of a game by securely sealing a control board box for the game machine, and capable of finding out the fraudulent act early if the fraudulent act is performed. SOLUTION: By superposing sealing members 20 and 30 and forcing a sealing clamp 11 into insertion holes 30c and 20a, a lock pawl 11c is locked with a lock surface 20b, and a head 11b is engaged with an engagement hole 30a. As a result, a box body 41 and a box lid body 42 are connected with each other in such a way as being unsealable. In this case, the lock surface 20b is formed to be disposed on the box body 41 side or on the box lid body 42 side (on the right side in the figure 5) of the sealing member 11. Accordingly, even if a through hole is bored by a drill, etc. on a skirt part 30f of a sealing member 30 and on a side wall 20d of a sealing member 20, the lock pawl 11c cannot be pressed on the plate part 11a side by a wire body such as a music wire inserted into the through hole, and therefore, detachment of the sealing clamp 11 can be prevented. In this way, a fraudulent act such as applying a fraudulent process to a control circuit board can be prevented. COPYRIGHT: (C)2005,JPO&NCIPI
