<p>PROBLEM TO BE SOLVED: To make a game ball flow down from a warp passage to a stage part without the occurrence of a ball jam.SOLUTION: A warp passage 200 for guiding a game ball to a stage part 80 includes: an inflow port 202 which allows the game ball to flow in; a discharge port 203 for discharging the flow-in game ball to the end part of the stage part 80; and a guide passage 210 for making the game ball flow down from the inflow port 202 to the discharge port 203. The guide passage 210 includes: an inclined passage 230 which inclines downward from the inflow port 202 to the discharge port 203; a flow-down direction converting part 305 for converting the flow-down direction of the game ball: a drop passage 240 extended in a vertical direction from the downstream of the inclined passage 230; and a bottom 241 formed in the drop passage 240 to guide the dropped game ball to the discharge port 203. The drop direction length of the drop passage 240 is set to such a length that only one game ball can drop. The flow-down direction converting part 305 is provided with a projecting part 305 which converts the flow-down direction of the game ball to the vertical direction upon contact with the game ball flowing down through the inclined passage 230.</p> |
