PROBLEM TO BE SOLVED: To provide Pachinko ball discharge device 4 that is simple in structure, performs discharge smoothly and reliably and can be made compact in size. SOLUTION: This Pachinko ball discharge device 4 has a ball passage 9 provide between a Pachinko ball guiding groove and a Pachinko ball discharge groove, and a ball controlling rotor 12 that controls the flow of Pachinko ball by facing engagement pawls 12b onto the ball passage 9. The ball passage 9 and the ball controlling rotor 12 are arranged so that the pressure of a Pachinko ball acts toward nearly the center of rotation of the ball controlling rotor 12, the engagement pawls 12b of the ball controlling rotor 12 are formed into a half-crescent shape to whose inward curved surface, the spherical surface of a forced out Pachinko ball fits and whose near surface is projected in an out ward curve and the height of the half-crescent is made lower than the diameter of the Pachinko ball.
