Abstract
A drive mechanism and a gripper mechanism equipped with the drive mechanism are provided. An electrical gripper includes a drive mechanism equipped with a motor, a feed screw that transmits a rotary drive force from the motor to a feed nut capable of displacement in an axial direction, and a gripper section that grips a workpiece by coupling to the feed nut and being displaced thereby. The drive mechanism further is constituted by a self-locking mechanism, which prevents the feed nut from being retracted as a result of a reactive force received in the event that the feed nut is advanced and the workpiece is gripped by the gripper section.
