ることができない問題があつた。 For example, when calibrating a width gauge for a material testing machine by applying an actual displacement, in conventional equipment, a fixed upper spindle and an elevating spindle face each other with a gap in a vertical line, and each An arm and a lower arm protruded horizontally, and an iron core-side jig and a coil-side jig of the differential transformer were engaged with these upper and lower arms, respectively. Therefore, the axis of the spindle that applies displacement and the axis of the differential transformer core are separated by a certain square distance. For this reason, there has been a problem in that the displacement of the spindle cannot be accurately applied to the differential transformer due to fitting tolerances between the spindle and its mounting portion, squareness accuracy, and distortion of the arm due to the spring pressure of the width gauge.
