PROBLEM TO BE SOLVED: To reduce initial shift errors as possible of a structure that supports an integrated block, which can be used as a load cell strain generator or Roberval mechanism. SOLUTION: A support member 3 is provided at a side edge 1a of a block main body 1, and the block main body 1 is supported horizontally by the support member 3. A load transfer member 5 is provided on the facing side edge, and the support member 3 and the load transfer member 5 are formed into almost the same shape and size, with them positioned in point symmetry, with a point P as a symmetry point. So a weight W load on a weighting dish 53 and a reaction W', which supports the weight are almost on the same axis L2 to suppress causing a complex stress to the block main body 1. As a result, the initial shift error of the support structure, shown in the figure is suppressed to minimum.
