摘要： Disclosed is a carrier moving mechanism for preventing occurrence of the backlash between a screw shaft and a carrier transmitted by this screw shaft. This carrier moving mechanism comprises a screw shaft and a carrier having secured thereon first and second nuts having teeth to be engaged with the lead of this screw shaft, in which the teeth of the first nut are brought into contact with one side face of the lead of the screw shaft and the teeth of the second nut are brought into contact with the other side face of the lead of the screw shaft and the carrier is moved through these first and second nuts by rotation of the screw shaft. This carrier moving mechanism is characterized in that the carrier moving mechanism comprises a supporting mechanism which supports one of the first and second nuts on the carrier so that the supported nut can be rotated in the rotation direction of the screw shaft but the movement of the supported nut in the axial direction of the screw shaft is restricted, bias means for biassing the supported nut to rotate the supported nut in the direction eliminating the backlash and inhibiting means for inhibiting the supported nut from rotating in the direction opposite to the above backlash-eliminating rotation direction, whereby occurrence of the backlash to be caused by wearing of the teeth of the supported nut and/or the lead of the screw shaft is prevented.
