PROBLEM TO BE SOLVED: To provide a polishing device capable of reducing the frequency of the work of exchanging a polishing member or easily performing the exchange work, with respect to the polishing device for polishing and lifting game balls to be used in a Pachinko machine. SOLUTION: A conveyor belt 11 which goes around is included and a freely attachable and detachable polishing member 201 and an attracting member 202 are arranged by facing the side where the conveyor belt 11 is elevated. The game balls are polished and lifted while being held between the conveyor belt 11 and the polishing member 201. Since the attracting member 202 attracts a part of dirt removed by the polishing member 201, the polishing member 201 is used for a long period of time. Thus, the frequency of the exchange work of the polishing member 201 is reduced. COPYRIGHT: (C)2005,JPO&NCIPI
