PROBLEM TO BE SOLVED: To provide a game machine capable of improving assembly work efficiency despite usage of a screw member of which head is to be separated, and capable of reducing troubles caused by the separated head.SOLUTION: A board box 92 of a main control device 63 comprises a front side component 101 and a rear side component 102. A cover member 154 is fixed to the rear side component 102. A fracture screw 170 comprises an area having a head to which a tip of a tool such as a screw driver can be inserted and an area having a shank where thread groove is formed, and these areas are connected with a fracture part. After the cover member 154 is fixed, the fracture part is cut off and thereby the head is separated from the fracture screw 170. The separation of the head makes it impossible to rotate the shank, and therefore a fixation of the cover member 154 becomes impossible to be released. The separated head is configured not to be moved apart from the shank more than a prefixed distance.SELECTED DRAWING: Figure 9 |
