PROBLEM TO BE SOLVED: To provide a game machine provided with a control box which can not be easily opened and can easily confirm the trace of being illegally opened. SOLUTION: In the game machine, the periphery of a through-hole 22b2 to which a bolt pin 40 is to be inserted is covered with a metallic protective plate 51 from the outer side, thereby preventing the periphery of the through-hole 22b2 demonstrating the restraining force of the pin 40 from being destroyed from the outside. Since the protective plate 51 is formed by extending pin receiving plates 53a and 53b for holding the tip parts 42a and 42b of the pin 40 in a falling prevention state, when the pin receiving plates 53a and 53b are removed so as to release the falling prevention state of the tip parts 42a and 42b of the pin 40, the protective plate 51 on the outer side is also removed. Thus, the trace of the removal of the pin receiving plates 53a and 53b is easily found from the outer side and the failure that the pin receiving plates are removed and sealing is released is dissolved.
