Claims

[Claims for Utility Model Registration] 1. An operating piece is screwed into a rotating threaded rod connected to a rotary body that can be rotated forward and backward by a motor, and as the rotating threaded rod rotates, the operating piece is moved left and right in the axial direction of the rotating threaded rod. a first threaded rod into which is screwed a first stopper that comes into contact with the operating piece when it slides in one direction and stops the rotation of the motor; A second threaded rod is provided with a second stopper screwed into it, and both the first and second threaded rods are rotatable.
and a fixed position stopping mechanism, characterized in that the second stopper is configured to be slidable left and right in the axial direction. 2 The ends of the first and second threaded rods are configured to be movable in the sliding direction as the actuating piece further slides after the first and second stoppers come into contact with the actuating piece; 2. The fixed position stopping mechanism according to claim 1, further comprising a switch provided at a destination of movement of the end of the threaded rod for stopping rotation of the motor by coming into contact with the end. 3. The fixed position stopping mechanism according to claim 1, further comprising a switch for stopping the rotation of the motor at the contact portions of the operating pieces of the first and second stoppers.
