Abstract: PURPOSE: A turnbuckle having a load cell is provided to mount a mounting object to a specific site with a circular scale detecting plate and scale installed to a tip of a gap adjusting screw. CONSTITUTION: A gap adjusting screw(3,3') forming a ring(6,6') is assembled to a clamping nut(2,2') toward right and left directions. A circular scale indicating plate(4,4') is formed to an inner tip of the gap adjusting screw. Scale(5,5') is formed to a side of the clamping nut to indicate a gap. A tubular center portion(7) is formed to a middle portion of the clamping nut. A load cell(9) is composed of a strain gauge by processing an installing portion(8) from an upper side forming scale. The load cell is mounted to a turnbuckle(1). Therefore, a mounting object is mounted to a precise site by controlling a precise mounting site of the gap adjusting screw. Displacement of the gap adjusting screw and load on the clamping nut are measured by installing the load cell to the installing portion.
