PROBLEM TO BE SOLVED: To provide a winning port opening/closing mechanism by which the erroneous closure of an opening/closing member caused by the impact of a game ball and the damage or failure of a winning device are prevented in the winning device of a pachinko game machine. SOLUTION: The opening/closing members 16 for opening and closing a winning port 15 are pivotally supported by spindles 17 in a vertical direction so as to be horizontally turned and guide paths 18 capable of guiding the game balls to a winning area 11 are formed at the opening/closing members 16. The opening/closing members 16 are horizontally turned through a turning drive means 19 and conversion-controlled to an opening position at which the guide paths 18 are communicated with the winning area 11 to guide the game ball to the winning area 11 and a closing position at which the winning port 15 is shielded. Thus, the direction in which reaction by the impact of the game ball acts and the turning direction of the opening/closing members 16 become almost orthogonal and the erroneous closure of the opening/closing members 16 due to the reaction is prevented. Also, since the spindles 17 pivotally supporting the opening/closing members 16 are in the same direction as the falling direction of the game ball, the impact at the time of receiving the game ball is hardly transmitted to the spindles 17 and the damage and failure of the winning device 3 due to the impact are prevented.
