<p><P>PROBLEM TO BE SOLVED: To provide a spreader shoe making a coefficient of friction between plate materials lower, and a friction reducing method. <P>SOLUTION: A friction reducing structure 11 of a spreader shoe 1 includes two plate materials 4a and 4b overlapping each other, a supporting plate 5 for supporting the plate material 4a, a holding device 6 for slidably holding the plate material 4b, and a lubricating liquid supply device 8 for infilling a lubricating liquid 7 between the plate materials 4a and 4b. The plate material 4a is provided with a groove 4c for storing the lubricating liquid 7 on a surface abutting on the plate material 4b, and a plurality of through-holes 4d for feeding the lubricating liquid 7 to the groove 4c through the plate material 4a. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
