PROBLEM TO BE SOLVED: To provide a polishing device capable of polishing game balls without increasing the size of the device and enabling an easy replacement of a polishing cloth.SOLUTION: A polishing device 1 includes a pair of guide rails 2 attached to a pachinko game machine in a manner inclined in a longer direction, and a polishing unit 3 detachably provided to the guide rails 2 and a polishing cloth 4 is provided on a bottom face part 3a. The polishing machine 1 polishes a game ball 10 by causing the game ball 10 to roll by self-weight on the pair of guide rails 2, and causing the underside of the game ball 10 to contact the polishing cloth 4. The polishing unit 3 can be easily attached to the guide rails 2 or easily detached from the guide rails 2 by causing an elastic deformation of the polishing unit 3 so as to move abutting parts 3b in the shorter direction toward outside, and thereby causing an interval between each abutting part 3b to become wider than the width of the pair of guide rails 2.SELECTED DRAWING: Figure 1 |
