Claims

[Claims for Utility Model Registration] 1. A tool for measuring the torsion of a rod-shaped object having at least one plane in the longitudinal direction, a pair of the same shape being respectively attached to both ends of the object to be measured. The measurement platform is formed into a thick plate shape with a polygonal outer shape, and at least both ends are formed on the same plane corresponding to each side of the polygon. A tool for torsion measurement, characterized in that a reference surface is formed, and a fitting hole is bored in the center of the object into which the object to be measured is fitted in a fixed state around its axis. 2. The measurement platform is formed in the shape of a thick plate with a polygonal outline, and a measurement reference surface is formed corresponding to each side of the polygon, and a mounting hole is drilled in the center. and a reference base plate portion having an outer peripheral surface shape corresponding to the inner peripheral surface shape of the mounting hole of the reference base plate portion, and a fitting hole having a shape corresponding to the cross-sectional shape of the object to be measured in the center portion. 2. The torsion measuring tool according to claim 1, wherein the torsion measuring tool is divided into two parts: an inserting tool that is drilled and fixed by being inserted into a mounting hole of the reference base plate part.
