摘要： The device includes a tubular case having a through hole that extends therethrough in an axial direction, a test indicator capable of determining a minute amount of change of distance by a stylus, a tubular holder body rotatably attached to the case through the through hole, a supporting body for supporting the holder body, a slidable body provided on a radial inner side of the holder body and movable relative to the holder body along the axial direction, and a pivotal body having a pivotable leading end portion whose pivotal amount is transmitted to the slidable body. The slidable body has an axial extension portion formed along the axial direction and a radial extension portion formed along the radial direction. The stylus and the radial extension portion are configured to come into contact with each other.
