PROBLEM TO BE SOLVED: To make it difficult to do a fraudulence, to thereby improve the crime- preventive mechanism of a pachinko game machine. SOLUTION: A locking apparatus for the pachinko game machine which has one frame and the other frame being openable/closable like a door with respect to the one frame, locks the other frame, and comprised of a plurality of brackets 7, a plurality of engaging claw 20, an elastic member 24, an unlocking member 17, and an unauthorized unlocking preventing mechanism. The brackets 7 are arranged on the one frame, and the engaging claw 20 are arranged on the other frame to engage with the respective brackets 7, to thereby carry out locking. The elastic member 24 holds the engaging claw 20 at a locking position, and the unlocking member 17 moves all the engaging claw 20 from the locking position to an unlocking position against an elastic force of the elastic member 24. The unauthorized unlocking preventing mechanism is arranged between the unlocking member 17 and the engaging claw 20, and upon movement of the unlocking member 17 from the locking position to the unlocking position, transmits the movement of the unlocking member 17 to all the engaging claw 20. However, when the engaging claw 20 singly move from the locking position to the unlocking position, the mechanism does not transmit the movement of the engaging claw 20 to the unlocking member 17.
