According to the present invention, provided is an opposite sliding door operating device, which comprises: a central rail mounted in an inner center of a door in a longitudinal direction of a vehicle body, and formed in a curved shape to move the door to the outside of a vehicle when the door is opened; a central roller mounted on the vehicle body to correspond to the central rail, and moving the central rail by having a central bearing part formed on one side to be seated on the central rail so as to be coupled to the central rail when the door is opened and closed; a lower rail mounted on a lower portion of the vehicle body in the longitudinal direction of the vehicle body, and formed in a curved shape to move the door to the inside of the vehicle when the door is closed; and a lower roller mounted on a lower portion of the inside of the door to correspond to the lower rail, and having a lower bearing part formed on one side to be seated on the lower rail to be coupled to the lower rail so as to be moved along the lower rail when the door is opened and closed. The central roller has a central shaft at a position separated from the center bearing part, and the lower roller has a lower shaft at a position spaced apart from the lower bearing part, such that the central shaft and the lower shaft rotate the central roller and the lower roller, respectively. According to the present invention, a moving structure of a door is simplified by using the curved central rail and lower rail. In addition, the central roller and the lower roller formed with a rotary shaft move the door to the inside/outside the vehicle body without a separate link structure required for opening and closing, manufacturing of the present invention is easy, and costs thereof are reduced. 본 발명은, 도어의 내측 중앙에 차체의 길이 방향을 따라 장착되되 도어의 개방 시 도어가 차량의 실외 측으로 이동되도록 곡선으로 형성된 센터레일; 센터레일에 대응 되도록 차체에 장착되며 도어의 개폐 시 일측에 형성된 센터베어링부가 센터레일에 안착됨에 따라 센터레일과 결합되어 센터레일을 이동시키는 센터롤러; 차체의 하부에 차체의 길이 방향을 따라 장착되되 도어의 폐쇄 시 도어가 차량의 내부를 이동되도록 곡선으로 형성된 로워레일; 및 로워레일에 대응 되도록 도어의 내측 하부에 장착되며 도어의 개폐 시 일측에 형성된 로워베어링부가 로워레일에 안착됨에 따라 로워레일과 결합되어 로워레일을 따라 이동되는 로워롤러;를 포함하며, 센터롤러는 센터베어링부와 이격된 위치에 센터축이 형성되고 로워롤러는 로워베어링부와 이격된 위치에 로워축이 형성되어 센터축 및 로워축은 각각 센터롤러 및 로워롤러를 회전시키는 것을 특징으로 하는 대향형 슬라이딩 도어 작동 장치를 제공하는 것을 특징으로 한다. 본 발명에 따르면, 곡선의 센터레일과 로워레일을 활용하여 도어의 이동구조를 단순화 시킨 이점이 있다. 또한 본 발명은, 회전축이 형성된 센터롤러 및 로워롤러가 별도의 개폐에 필요한 링크 구조 없이 도어를 차체의 실내외 측으로 이동시키며 제조가 용이하고 원가가 절감되는 이점이 있다.
