  • Patent number: 5813282
    Abstract: A powered sliding-door system of an automobile with a sliding-door drive device A and an automatic door closer B. The sliding-door drive device A has a box-like case body 1 opening downward, a case cover 2 covering the opening of the case body 1. A pair of guide pulleys are rotatably supported by axes, and each axis stands on the front end and the rear end of the case in slanting posture. A loop of cable is arranged between the pair of guide pulleys so that a working side is arranged outside of the case body and a return side is arranged in the case body. The loop of cable is driven by an motor driven actuator 12.
