SOLUTION: The pachinko game machine has a ball feeding sprocket 413 for feeding one game ball among game balls on an aligning passage 416 in the state separate from the following game balls whenever one game ball is shot by a shooting device. Opening parts 601a, 601b and 601c whose widths are narrower than the diameter of the game ball are formed on at least one of the upper surface, side surfaces and lower surface of a moving passage 414 on which game balls to be fed to a pumping unit by the ball feeding sprocket 413 move toward the pumping unit.
