PROBLEM TO BE SOLVED: To provide a game machine capable of favorably polishing game balls to be used circulatingly in the game machine.SOLUTION: In a polishing passage 259, each game ball is sandwiched between a polishing member 251 and an inside wall of a spiral groove 271 formed in the inside wall of the polishing passage 259. Consequently, the game ball constantly comes into contact with the polishing member 251 in the polishing passage 259. A contact member 248 comes into close contact with an outside wall of a polishing-passage forming member 251 for forming the polishing passage 259. The contact member 248 is mounted on a rotor 249 and is rotated by drive of a polishing drive part 113 of the rotor 249. The polishing-passage forming member 245 is also rotated by receiving the rotation of the contact member 248. The game ball receives force from the inside wall of the rotating spiral groove 271 to rotate with it coming into contact with the polishing member 251.SELECTED DRAWING: Figure 17 |
