However, in order to prevent the ball feeding member from coming off as described above, the E-ring is naturally required in the case of using the former E-ring, and the cost is high and the E-ring cannot be attached. There is a task that takes time. Further, in the latter case where the tip of the horizontal axis is stopped by the cover body, the cover body is removed when cleaning the supply passage, so that the ball feeding member may come off the horizontal axis, resulting in poor workability. There were challenges. Therefore, the present invention provides a hitting ball supply device for a pachinko machine, which can solve the problems seen in the related art.

[0004]

In order to achieve the above object, the present invention contemplates a supply passage on the back side of the front frame for guiding the pachinko balls of the hitting ball supply tray in a line, and a terminal portion of the supply passage. In the hitting ball feeding device of the pachinko machine, a ball feeding member that blocks the flow of the pachinko balls by one and receives the pachinko balls one by one by the rotation and sends them to the launch position of the launch rail is rotatably provided on the horizontal axis. The ball feed member is inserted into the horizontal shaft in a state of being rotated upward, and the engaging portion that engages in a state of being rotated downward by natural return is provided at a position where the body portion of the ball hitting supply device and the ball feeding member face each other. I decided to set each other.

Further, the engaging portion has a function as a stopper.
