Abstract: 본 발명은 지렛대의 원리를 이용한 회전체의 구동 장치에 관한 것이다. 
     지렛대는 이의 원리가 막대의 받침점(지렛목)의 이동에 따라 힘의 이득을 볼 수 있게 하고 있기 때문에 이를 산업적으로 이용하고 있는 것이 바로 가위나 집게 등이 그 한계가 되고 있는 것이다. 
     이와 같은 지렛대는 힘의 이득이 막대의 받침점(지렛목)의 수평 이동임으로 이는 물체의 직선 운동에만 국한하여 이용되고, 구동 장치의 회전 운동으로는 이용이 불가능 하였던 것이다. 
     한편, 각종 공작 기계나 운반 기계 등의 산업 기계의 모터나 엔진의 경우에는 시동 시에는 많은 기동력이 소요되기 때문에 여유 동력을 마련해야 하고, 또한 구동이 끝나고 정지 시에는 급정지가 요구되나, 이와 같은 경우는 전동 및 구동 물체에는 회전 관성력이 작용하고 있기 때문에 급정지가 불가능하여 안전사고나 작업성 저하 등의 결점이 있었던 것이다. 
     본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명 요지는 직선 막대를 곡선 막대로 하고, 곡선 막대의 일정 지점에 설치된 지지 로울러를 받침점(지렛목)으로 하되, 가해진 힘을 받는 쪽의 회전 거리는 짧게 하고, 힘을 가하는 쪽의 회전 거리는 길게 하되, 회전체의 축심은 3각 선상으로 배치된 외접 및 내접 지지 로울러에 의해 이루어지게 함으로서 지렛대의 직선 운동을 구동체의 회전 운동으로 전환하여 산업에 다용도 이용이 가능케 한 것이다.
