PROBLEM TO BE SOLVED: To provide a game machine using a fracture screw, capable of effectively preventing an erroneous fracture of the fracture screw and enabling an easy performance of coupling work.SOLUTION: There is provided a game machine in which two pieces of constituent members 432, 450 are coupled with a fracture screw 651 where a separation part 654 is formed at a head part 652, the separation part being a portion having a screw hole (engagement part) for a driver (operation tool) DR1 to be engaged with, the portion capable of being fractured and separated if rotated with a torque still larger than a torque necessary for the coupling. It is so configured that a housing member 621 is provided as a protection member to cover a portion excluding the screw hole of the separation part 654 in a state before the fracture screw 651 is fractured.SELECTED DRAWING: Figure 26 |
