PROBLEM TO BE SOLVED: To constitute a device for making a polishing material flow in the axial direction simply, for example, in a polishing device for storing the polishing material and an article to be polished in a polishing tank and polishing the article to be polished by the flow of the polishing material by the rotation of the polishing tank. SOLUTION: The phase of the tops a,... of the polygon on one side of a polishing tank 6 as a hollow vessel with a polygonal section is made different from that of the tops b,... of the polygon on the other side. At the constitution time of a wall surface, its production is facilitated by combining triangle shape plates 12,... with no twisting. Further, when the section shape of the polishing tank 6 is a regular n-sided shape, the shift of the phase of a top is made by 360 deg./2n. |
