PROBLEM TO BE SOLVED: To prevent a fraudulent intruder such as a cell plate from a connected part of a ball feeding passage from entering, and surely prevent a fraudulent act such as unlawfully opening a big winning port of a special variable winning device from occurring by providing a fitting structural part of a cut off part and a protruding part in the middle of the ball feeding passage which is provided on the rear mechanism panel of a game panel. SOLUTION: A ball feeding passage which guides the flowing down of game balls discharged from a ball discharging device to an upper tray, has a feeding passage 20 which is provided on a rear mechanism panel 120, and an upper tray communication passage which is provided on an opening/closing panel. On the rear surface side of a game panel, a cut off part 41 is provided in a manner to communicate the upper tray communicating passage and the feeding passage 20, and around the cut off part 41, a groove part 42 which is formed into an approx. L-shape along the upper side and the left side of a ball relaying passage 40, is formed. Then, on the front surface side of the rear mechanism panel 120, a protruding part 21 which can be fitted in the groove part 42 is provided, and by fitting both parts 21, 42 under a state wherein a front surface frame and the rear mechanism panel 120 are closed, a fraudulent intruder is prevented from entering an electric part on the rear surface side of the game panel through the ball feeding passage.
