<P>PROBLEM TO BE SOLVED: To compensate for relative positions of a lateral beam and a support column by relatively pivoting the two with a positioning column as an axis, and to increase the rigidity between the lateral beam and the support column using elastic members. Ž<P>SOLUTION: A relative position error absorbing means for a double-driver synchronous movement positioning plate form is disposed between the lateral beam A1 and the support column A2 of the double-driver synchronous movement positioning plate form A and includes the positioning column 10 and at least two elastic members 30; wherein the positioning column 10 is pivotally fitted in the lateral beam A1 and the support column A2 so that the lateral beam A1 and the support column A2 can compensate for their positions by relatively turning around the positioning column 10 as their axis, and at least two elastic members 30 are disposed between the lateral beam A1 and the support column A2 to push up the lateral beam A1 from its both sides, where the elastic member 30 on one side of the lateral beam A1 is compressed when the lateral beam A1 and the support column A2 are relatively turning.
