The present invention relates to a force reflecting system which couples a variable stiffness actuator using a magnetorheological elastic body to a finger wearing part, thereby controlling stiffness of the magnetorheological elastic body and controlling a resistance force which is delivered to a finger when moving the finger. Also, the present invention has a simple structure and is easily manufactured by using the magnetorheological elastic body. The force reflecting system applying a variable stiffness actuator using a magnetorheological elastic body comprises the finger wearing part and a variable stiffness actuator. 본 발명은, 자기 유동성 탄성체를 이용한 가변 강성 구동기를 손가락 착용부와 결합시킴으로써, 상기 자기 유동성 탄성체의 강성을 제어하여 손가락이 움직일 때 손가락에 전달하는 저항력을 제어할 수 있다. 또한, 자기 유동성 탄성체를 이용함으로써, 구조가 간단하면서도 제작이 용이한 이점이 있다.
