Abstract
Provided is a measuring devicefor measuring the size of an object comprising a body, and a spindlewhich is screwed into the bodyand axially advances and retracts by screwing with respect to the body, the measurement being based on the axial displacement of the spindleeffected by the revolution of the spindle, wherein the spindle is screwed into the bodyvia a multiple-start thread. Therefore, it is possible to displace the spindleat a high speed, which improves the operability of the measuring device.
