PROBLEM TO BE SOLVED: To provide a lifting and polishing device capable of realizing a stable lifting circulation with a simple and compact mechanism, easily attaching a polishing mechanism, stably supplying a polishing sheet, sufficiently managing an abnormality of the polishing sheet and easily exchanging the polishing sheet. SOLUTION: This lifting and polishing device of game balls is provided with a lifting mechanism 1 for lifting the game balls B from a game ball recovery part RT, a lifting path 2 for leading the game balls B from the lifting mechanism 1 to a game ball supply part ST and the polishing mechanism 3 for polishing the game balls by being in frictional contact with the game balls B being lifted. Opening parts 22a and 22b for polishing are formed along the lifting path 2, the polishing mechanism 3 holding a roll polishing sheet S is made to face the opening parts 22a and 22b and the game balls B being lifted are polished. |
