PROBLEM TO BE SOLVED: To improve the capacity of ball polishing and to prevent loss of a polishing material by connecting a drive rubber roller with a paying-out roller and controlling rotation of the paying-out roller so as to adjust the paying-out speed of a polishing member. SOLUTION: In polishing pachinko balls in this pachinko ball polishing device, a polishing member 6 is paid out from a paying-out reel 7 via a drive rubber roller 9 by rotation of a paying-out motor, moved sliding on the surface of a back plate 14, and wound up by a winding reel 8. Since the back plate 14 is slippery and has no pleated protrusion, the friction resistance with the polishing member 6 becomes smaller to enable the polishing member 6 to be smoothly fed. Since the polishing member 6 is directly driven, constant speed paying-out is enabled and, since the paying-out motor is independent, the paying- out speed of the polishing member 6 can be controlled by intermittent operation or changing the rotation speed.
