PURPOSE:To enable prevention of the secondary contamination after cleaning by supporting to hold a plate in the air with the contact points of the rings of a support material and a stopper shaft. CONSTITUTION:A pair of square frames 24, 24' are installed vertically in parallel with the direction (arrow-mareked direction A) of inserting a plate 11 on both ends of a bottom plate 26. Between these frames 24, 24', support materials 23, 23' are installed in upper and lower two stages perpendicular to the arrow- marked direction A. These support materials 23, 23' consist of plural number of rings 21, 21' which are each gradually thinner from the center toward the circumference are penetrated in series with a shaft 22 installed between the frames 24, 24'. These materials 23, 23' hold the plate 11 between the side walls of the adjacent rings 21, 21' at the contact points of both upper and the lower ends of the plate 11. At the end of the direction wherein the plate 11 is inserted between the frames 24, 24', stopper shafts 25, 25' are also installed perpendicular to the arrow-marked direction A. In this construction, stagnation of water used for washing is prevented. |
