ABSTRACT:
Two horizontal holes are processed at the end face of a movable pillar of a load measuring cell in a block shape. A power-point spring is formed between the horizontal holes, and the internal side faces of the horizontal holes constitute the internal end faces of supporting-point springs. Further, from above or below the load measuring cell, a vertical hole is processed so that the supporting-point springs are separated by the vertical hole extending in a vertical direction and are formed on both side faces in the longitudinal direction of load measuring cell.
