Abstract:
This drive screw device is provided with: a drive screw; a drive unit which causes the drive screw to rotate; a slider which moves along the drive screw by means of the rotation of the drive screw; and an external load which is provided on the drive screw and applies a rotational load to the drive screw. By this means it is possible to provide a drive screw device with which there is little pressure variation even if a frictional force varies.
