To provide the winning device of a pachinko game machine capable of controlling the easiness of ball entry to two path exits provided inside a large winning port by a structure simpler than the one of a conventional item.

On the inner side of the large winning slot 5, a first path exit 13 at a leftward position and a second path exit 15 at a rightward position are formed. A floor surface 17 provided between the first path exit 13 and the second path exit 15 is turned to a down slope from the side of the second path exit 15 to the side of the first path exit 13. A back-and-forth moving member 9 is supported on the side of a main body 3, is capable of moving in a back-and-forth direction, is piled up on the upper side of the floor surface 17 at the time of forward movement and is not piled up on the floor surface 17 at the time of backward movement. The upper surface 9a of a part to be piled up on the floor surface 17 at the time of the forward movement is turned to the down slope from the side of the first path exit 13 to the side of the second path exit 15. Thus, just by operating the back-and-forth moving member 9 back and forth, the state of making a ball easily enter the first path exit 13 or the state of making the ball easily enter the second path exit 15 is attained.
