PROBLEM TO BE SOLVED: To provide a pinball game machine capable of preventing a player from having a bad impression or from refraining from continuing the play because of the bad impression by reducing the possibility for a seemingly temporarily winning game ball to drop out. SOLUTION: The pinball game machine includes an electric generator which has a winning hole 25, a pair of movable wing pieces 21 and 22 disposed on both side of the winning hole 25, and a driving means for driving the movable wing pieces 21 and 22 between the closed state in which the movable wing pieces 21 and 22 are raised and the opened state in which the angleαof the movable wing pieces 21 and 22 to the vertical direction P is larger than the angle in the closed state. In the pinball game machine, the wing length of one movable wing piece 22 is longer than the length of the other movable wing piece 21. COPYRIGHT: (C)2008,JPO&INPIT
