PROBLEM TO BE SOLVED: To effectively prevent a fraudulent act to a board box of a game machine.SOLUTION: An upper bracket and a lower bracket 730 which are extended in the middle of connection between a first box and a second box are covered with a sealing cap 800 in a slide direction. A locking wall 828 of the sealing cap elastically deforms a lock piece 745 of the lower bracket and rides over the nib 746 for locking mutually. In a connection state of the boxes, since a vertical wall 640 extended from the upper bracket enters a portion between an inner vertical wall 826 of the sealing cap and the lock piece to regulate the elastic deformation of the lock piece, locking between the nib 746 and the locking wall 828 cannot be released. Thus, the sealing cap cannot be removed, access to a connection portion between the upper bracket and the lower bracket is prevented, and thereby the connection of both the boxes cannot be released fraudulently. |
