PROBLEM TO BE SOLVED: To provide a pachinko game machine to enhance an efficiency of locking operation. SOLUTION: The locking device of the pachinko game machine has a lock mechanism 50 locking an engaging pawl member 30 present on an unlocking position to the above position and unlocking the locking condition when a second frame is closed to substantially fully closed position relative to a first frame, and an inclined face 35d formed the distal end portion of the engaging pawl 35 of the engaging pawl member 30, and capable of abutting to the pawl receiving of the second frame in a condition where the lock condition of the locking mechanism 50 is released and the engaging pawl 35 thereof is not engaged to the pawl receiving member of the second frame. The inclined face 35d is constituted so as to be able to converting the closing force of the second frame transmitted to the inclined face via the pawl receiving member of the second frame to the sliding force in an unlocking direction of the engaging pawl member 30. Consequently, the engaging pawl 35 in the disengaging condition can be engaged to the receiving member of the second frame by applying a closing force to the second frame in the case such that one of the engaging pawl 35 of the engaging pawl member 30 comes off from the pawl receiving member of the second frame.
