PROBLEM TO BE SOLVED: To provide a game ball lifting machine facilitated in operation for exchanging polishing cloths and free from trouble when lifting.SOLUTION: A narrow polishing material 11 having a width set according to a diameter of a game ball P is employed, and thus the polishing material 11 is prevented from going slack in a width direction and can be easily changed. The polishing material 11 is stored inside a channel rail member 15, guides the game ball P via the channel rail member 15 and also moves the game ball P while pressing the game ball toward the polishing material 11, and thus the game ball P is also prevented from coming off from the channel rail member 15 and the game ball P is prevented from interference with each other, so that damage on a conveying belt 103 and the channel rail member 15 due to interference with the game ball P and jam of the game balls P are prevented, rest of lifting movement due to failure is also prevented and thus the occurrence of the trouble can be prevented. |
