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