PROBLEM TO BE SOLVED: To certainly move a door plate to a closed position without shortening the life of a motor, etc., by preventing the opening of a door plate in such a way that the drive of a door plate to a closed position can be continued even in the case where a playing ball is bited when a prize-winning port is closed. SOLUTION: This device is provided with a door plate 11 for opening and closing a prize-winning port in which a playing ball can win a prize, a motor 14 for driving the door pate 11 between an opening position to open the prize- winning port and a closed position to close the prize-winning port, and an oscillating member(OM) 16 of an example of an interlocking member that is deformed elastically by the resistance to prevent the drive which is produced when the door plate 11 is driven by the drive of the motor 14 from the open position to the closed positon. This OM 16 moves the door plate 11 to the closed positon by elastic resiliency, when the resistance is lost.
