Abstract
A thimble (5) and a spindle (4) are rotated through a first constant-force device (70) by rotating an operation sleeve (6) integrally having a first operation section (61) and a second operation section (62). When a more than predetermined load is applied to the spindle (4), the first constant-force device (70) is actuated to spin the operation sleeve (6) idly. Since the operation sleeve (6) integrally has the first operation section (61) and the second operation section (62), both double-handed operation for holding the frame by left hand and rotating the first operation section (61) by right hand and single-handed operation for holding the frame and rotating the second operation section (62) with a single-handed are possible while retaining the same operability as in conventional operation during measurement.
