The present invention relates to a loop coupling. More specifically, the loop coupling is mounted between a worm gear and a motor to automatically fold or unfold a screen, thereby being easily installed by anybody. The loop coupling includes an insertion groove which is formed on one end thereof and into which a leaf spring is inserted to compensate for a processing error generated during a process, thereby increasing a fastening force of the worm gear. The loop coupling also includes a sensor mounted on the other end thereof to control the rotation of the motor, thereby preventing overheating of a motor due to continuous rotation. |
