PROBLEM TO BE SOLVED: To provide a pachinko ball polishing machine, having high pachinko ball polishing ability. SOLUTION: A plurality of support rods 26 face a carrying belt 14 in parallel to it, and pachinko balls B are held and fed to be lifted by a groove 28 between the support rods 26 and the carrying belt 14. On a plurality of covers 36 disposed in the height direction of this pachinko ball polishing machine 10, a polishing cloth is installed to get in surface-contact with the pachinko balls B. Since the rotation radius of the pachinko balls B inserted into the groove 28 is smaller than the ball diameter, they are rotated a lot while they are fed to be lifted, so that they greatly get in contact with the polishing cloth 42 to be polished.
