PROBLEM TO BE SOLVED: To make the easiness of taking in a ball from an upper ball distribution body to a winning ball take-in part different from the easiness of taking in a ball from a lower ball distribution body to the winning ball take-in part. SOLUTION: In the case that the winning ball take-in part 30 is elevated to the upper ball distribution body 17 and the lower ball distribution body 29 and is stopped at an elevation limit position, since a narrow ball entrance 30b corresponds to the upper ball distribution body 17 and a wide ball entrance 30c corresponds to the lower ball distribution body 20, the ball is fetched from the lower ball distribution body 29 to the winning ball take-in part 30 more easily than from the upper ball distribution body 17 to the winning ball take-in part 30. In the case that the winning ball take-in part 30 is lowered to the upper ball distribution body 17 and the lower ball distribution body 29 and is stopped at a lowering limit position, since the wide ball entrance 30a corresponds to the upper ball distribution body 17 and the narrow ball entrance 30b corresponds to the lower ball distribution body 29, the ball is fetched from the upper ball distribution body 17 to the winning ball take-in part 30 more easily than from the lower ball distribution body 29 to the winning ball take-in part 30.
