Claims

[Claims for Utility Model Registration] (1) In a gripper that opens and closes fingers by converting rotational drive by a rotary actuator into linear motion, a rolling element that is rotatably supported on a base and rotationally driven by a rotary actuator. A rolling contact screw transmission mechanism consisting of a screw shaft and a nut using a screw shaft, and an opening/closing mechanism that opens and closes at least two fingers driven by the linear movement of the screw transmission mechanism. Grizpa to do. (2) In the gripper described in claim 1 of the utility model registration claim, the rolling contact screw transmission mechanism is
A gripper characterized by being equipped with a screw transmission mechanism of either a ball screw or a roller screw. (3) In the gripper described in claim 1 of the utility model registration claim, the finger opening/closing mechanism driven by the linear motion of the rolling contact screw transmission mechanism is either a link mechanism or a rack and pinion mechanism. Gritsupa is characterized by being equipped with a mechanism.
