PROBLEM TO BE SOLVED: To easily dissolve the clogging of game balls when the game balls are clogged in a ball discharge passage. SOLUTION: A stand plate part 6 of an inner frame is mounted with a board unit 50, and the board unit 50 is formed with the ball discharge passage 71 having an open front face. The ball discharge passage 71 discharges game balls, which in turn are discharged from an operation-start hole to the rear of a game board, to the outside of the machine, and the front face of the ball discharge passage 71 is closed by the stand plate part 6 with the board unit 50 attached thereto and is opened by the detachment of the board unit 50. When game balls are clogged in the ball discharge passage 71, the front face of the ball discharge passage 71 is opened based upon the detachment of the board unit 50 from the stand plate part 6, and the game balls in the ball discharge passage 71 are removed from the front face of the ball discharge passage 71 to dissolve the clogging of the game balls.
