PROBLEM TO BE SOLVED: To provide a ball delivering device of a pachinko machine which can reduce pressure of balls and prevent a failure of a driving motor, and prevent jamming of balls, and which can deliver the precise number of balls. SOLUTION: A ball delivering device is provided with supplying passages 19a and 19b, a lead screw 17 provided in parallel with the supplying passages 19a and 19b and having on an outer periphery a spiral ball feeding projected bar 22 which is faced in the supplying passages 19a and 19b, a driving motor for turning the lead screw 17 and a pachinko ball discharging passage 20 (20a and 20b) for discharging pachinko balls. A ball transferring space E surrounded by the outer periphery of the lead screw 17 and inside peripheries of the supplying passages 19a and 19b is set so that a distance between the outer periphery of the lead screw 17 and inside peripheries of the supplying passages 19a and 19b is larger than a diameter of one pachinko ball and smaller than a size of diameters of two balls. And a distance between a top surface of the ball feeding projected bar 22 arranged on the outer periphery of the lead screw 17 and the inside peripheries of the supplying passages 19a and 19b is set so as to be smaller than the diameter of one pachinko ball.
