PROBLEM TO BE SOLVED: To provide a game machine such as a Pachinko machine which prevents the fraudulent unlocking of a locking device. SOLUTION: The Pachinko machine 10 is equipped with an outer frame, a machine body frame 12 which is provided in the front part of the outer frame and is supported to open and close at a side of the outer frame, and a front door frame 13 which is provided in the front part of the machine body frame 12 and is supported to open and close at a side of the machine body frame 12. The locking device locks the machine body frame 12 to the outer frame and the front door frame 13 to the machine body frame 12. If a key is inserted into a cylinder lock 91 and is turned around in a direction, the machine body frame 12 is unlocked. If the key is turned around in another direction, the front door frame 13 is unlocked. If the fraudulent unlocking is attempted by inserting a piece of wire, or the like, between the outer frame and the machine body frame 12, an inside locking member placed behind the boundary between the outer frame and the machine body frame 12 prevents the fraudulent unlocking.
