본 발명에 따르면, 2 축 커플링 랙이 직선 운동을 하면 치합된 피니언이 회전하면서 피니언 회전축을 회전시키거나 또는 그 역으로 피니언 회전축이 회전하면 결합된 피니언이 회전하고 피니언에 치합된 2 축 커플링 랙이 직선 운동하는 통상적인 랙 & 피니언의 본질적인 기능에 더하여, 2 축 커플링 랙에 형성된 원주형 랙 기어를 따라 피니언 어셈블리를 통째로 360도 또는 소정 각도로 회전시킬 수 있으므로 랙 & 피니언의 기본적인 동력전달에 영향을 주지 않으면서 피니언 회전축에 결합된 임의의 회전대상을 또 다른 방향으로 추가로 회전시킬 수 있어, 2축 회전기능이 동시에 필요한 기기 예를 들면 2축 태양추미장치 등에 적용할 경우 큰 효과를 얻을 수 있다.
