PROBLEM TO BE SOLVED: To prevent a game ball flowing-down path from being jammed with game balls. SOLUTION: A branch path 47 which makes the game balls PB flow down to an upper tray path 74 or a lower tray path 75 is arranged to the upper tray path 74 and to the lower tray path 75 from a downflow path 38. The branch path 47 is provided with a retention part 77 which is made concave from an imaginary surface L along a sidewall 87 of the upper tray path 74 to get the game balls PB retained when the upper tray path 74 is filled to the full capacity and makes some of the game balls PB stick out to the side of the branch path 47 as compared with the imaginary surface L. Then, when the upper tray path 74 gets closer to the full capacity, the game balls PB are retained at the retention part 77 and some of the game balls PB retained stick out to the side of the branch path 47 from the imaginary surface L. As a result, the game balls PB get a new wall part M formed in the branch path 47. The wall part M guides the game balls PB flowing down to flow down to the side of the lower tray path 75, thereby preventing jamming the branch path 47 with the game balls PB.
