To provide a game machine capable of effectively preventing the erroneous fracture of a fracture screw and also easily performing tightening work in the game machine using the fracture screw.

In the game machine where components at two points are connected by the fracture screw which has a screw hole (engaging part) that a driver (operation instrument) is to be engaged with and has at its head part a separation part which is a part that can be fractured and separated when rotated by torque larger than torque required for tightening, the fracture screw is formed by bending a planar member and includes a housing member 658 as a protective member for covering a part excluding the screw hole of the separation part in the state before being fractured.
