とする円孔の内径変化測定器。 A change in the inner diameter of a circular hole, which is equipped with a displacement detector that extends two standards along the diametrical line from two points on opposing inner walls of the circular hole and detects the relative displacement of the standard standards in the diametrical direction. In a measuring instrument, a pair of displacement detectors with equal output changes due to temperature changes are placed in symmetrical positions, and the relative displacement of the standards causes the pair of displacement detectors to have equal magnitudes and opposite directions. An instrument for measuring changes in the inner diameter of a circular hole, which is characterized by a structure that transmits the displacement of
