When the movable piece is opened, the ball hits the opening, and the partition plate provided in the opening causes the ball to roll to the left and right overhanging portions of the concave chamber.

[Problems to be Solved by the Invention] By the way, as a modified example of the above-mentioned variable winning ball device, when the movable piece is opened by forming an opening in the front surface on the left and right of the concave chamber, the hitting ball is moved to the left or right. It is conceivable that the player wins in the opening and rolls into the central concave chamber. But,
In order to close the left and right openings with the movable piece, a blocking member may be provided on each of the left and right movable pieces, but when the movable piece is opened, the tip end part thereof sticks out from the variable winning ball device to the left and right. . However, since it is necessary to provide a nail or a windmill around the variable winning ball device in order to change the falling direction of the hit ball, when the movable piece is opened, the tip of the variable winning ball device is It is not preferable to protrude from the left and right.

Therefore, the main object of the present invention is to enlarge the prize winning space and allow the hitting balls to win from the left and right openings, thereby expanding the rolling range of the hitting balls, thereby sufficiently attracting the interest of the player. It is an object of the present invention to provide a variable winning ball device for a ball game machine.
