To provide a device of opening and closing a passage for game balls capable of reducing the number of components and assembly man-hours and reducing a component cost and an assembly cost.
One opening/closing member 92 is moved so as to be alternately inclined. A pair of weir parts 92a respectively close a pair of discharge ports 72 when the opening and closing member 92 is turned to a discharge port closing posture. Also, when the opening and closing member 92 is alternately inclined to both end parts from the discharge port closing posture and turned to a partial discharge port opening posture, the pair of weir parts 92a alternately open the pair of discharge ports 72 and the game balls flow in from the opened discharge port 72 into an inflow part 91a. One opening and closing member 92 is sufficient without the need of respectively disposing the opening and closing members 92 corresponding to the respective discharge ports 72.
