ABSTRACT:
Provided is a measuring device1for measuring the size of an object comprising a body2, and a spindle3which is screwed into the body2and axially advances and retracts by screwing with respect to the body2, the measurement being based on the axial displacement of the spindle3effected by the revolution of the spindle, wherein the spindle is screwed into the body2via a multiple-start thread31. Therefore, it is possible to displace the spindle3at a high speed, which improves the operability of the measuring device.
