PROBLEM TO BE SOLVED: To obtain a rotary table for a potter's wheel having the same function as that of a large-sized potter's wheel by easily setting it on a small-sized potter's wheel. SOLUTION: A cylindrical vessel is clamped by a bottom plate and a ceiling plate each having a diameter a little bigger than that of the vessel. A plurality of protrusions are mounted on the outer circumference of the upper surface of the bottom plate to fix the vessel. A plurality of protrusions are mounted on the lower surface to fix to the rotary table of the established small-sized potter's wheel. A plurality of protrusions are provided on the outer circumference of the lower surface of the ceiling plate to fix the ceiling plate to the vessel. The rotary table for the potter's wheel having the same function as that of the large-sized potter's wheel can be obtained in this way. COPYRIGHT: (C)2006,JPO&NCIPI
