Zusammenfassung:	Disclosed is a spring operating device for a circuit breaker capable of preventing backlash of a rotary motion unit during an opening/closing operation. The disclosed spring operating device for a circuit breaker may comprise: a rotary motion unit which rotates in one direction by applied driving force; a link unit connected to the rotary motion unit and performing linear reciprocating motion by the rotational force of an upper rotary motion unit; a spring connected to the link unit and performing a closing operation of the circuit breaker while being elastically deformed or restored according to the linear reciprocating motion of the link unit; and an anti-reverse rotation unit preventing rotation of the rotation unit in the reverse direction. 개폐 동작시 회전운동유닛의 백래쉬를 방지할 수 있도록 된 차단기용 스프링 조작장치가 개시되어 있다. 이 개시된 차단기용 스프링 조작장치는 인가되는 구동력에 의하여 일 방향으로 회전 운동하는 회전운동유닛과; 이 회전운동유닛에 연결되며, 상회전운동유닛의 회전력에 의하여 직선 왕복 운동하는 링크부와; 링크부에 연결되어, 링크부의 직선 왕복 운동에 따라 탄성변형 또는 복원되면서 차단기의 클로징 동작을 수행하는 스프링과; 회전운동유닛이 역방향으로 회전되는 것을 방지하는 역회전방지부를 포함할 수 있다.
