Abstract

Provided is a measuring device 1 for measuring the size of an object comprising a body 2, and a spindle 3 which is screwed into the body 2 and axially advances and retracts by screwing with respect to the body 2, the measurement being based on the axial displacement of the spindle 3 effected by the revolution of the spindle, wherein the spindle is screwed into the body 2 via a multiple-start thread 31. Therefore, it is possible to displace the spindle 3 at a high speed, which improves the operability of the measuring device.
