PROBLEM TO BE SOLVED: To provide a game machine which can improve the efficiency of assembly work even though screw members with head sections that can be separated are used and which can reduce defects by such separated head sections. SOLUTION: A substrate box 92 of a main control device 63 includes a front side construct 101 and a back side construct 102. A cover member 154 is fixed on the back side construct 102. A break screw 170 includes: a region with a head section into which the tip end of tools such as drivers can be inserted; and a region with a shaft section on which a screw groove is formed, wherein these regions are connected with each other by a break section. The head section is separated from the break screw 170 by the break section being disconnected after the cover member 154 is fixed. The shaft section can be no longer rotated as the head section is separated and the fixing of the cover member 154 cannot be released. The separated head section is retained inside a holder which is integrated with the break screw. COPYRIGHT: (C)2010,JPO&INPIT
