PURPOSE:To correctly adjust the irregularity of the right and left of a row piece individually respectively at the right and left, by connecting between members of each open parts of 1st and 2nd elastic members by bendable elastic connection member respectively and providing an adjusting member which adjusts respectively the bend states of each elastic members. CONSTITUTION:The interval between the members of each open part of 1st and 2nd elastic members 36, 38 is changed by adjusting the bend states of elastic connection members 44, 46 by adjusting members 48, 50 and the right and left heights of a row piece 16 are respectively adjusted. The height of the row piece 16 whole body can be adjusted by adjusting the bend states of both elastic connection members 44, 46 in the same, also, the row piece 16 can be inclined by adjusting in unbalance. Consequently, a throat height can be worked with high accuracy at high speed by grinding and polishing by using a surface grinder, surface lapping machine, etc., with the irregularity of the right and left of the row piece 16 being correctly adjusted individually respectively at the right and left. |
