PROBLEM TO BE SOLVED: To provide a game machine capable of preventing an unlocking action by a false external unlocking operation in a locking mechanism. SOLUTION: A locking receiving apparatus 18 constituting a locking mechanism 17 is constructed of a locking piece 20, a fixing board 22 and a protection board 23. While a locking hook 21 constituting the locking mechanism 17 is engaged with the locking piece 20, the locking receiving apparatus 18 is fixed on the left edge inside of an outer frame 11 so that the protection board 23 is positioned on the front end side of the locking hook 21. Therefore, the locking mechanism 17 is prevented from a false external unlocking operation by means of an external operation member because contact with the locking hook 21 is prohibited by means of the protection board 23 even if the external operation member is inserted from a gap in the periphery of this Pachinko machine.
