Abstract
In an automatic door operating system, there is employed a so-called fail-safe means which controls a door closing device. The door closing device functions to enforcedly shift the door from its half-latch position to its full-close latched position. The fail-safe means is so arranged as to deal with such a possible undesirable matter that due to, for example, a foreign thing accidentally caught between the door and the vehicle body, the door is forced to stop during its shifting from the half-latch position to the full-close latched position. Upon this door stopping, a control switch is turned in the other direction by an operator (viz., driver). With this, the door closing device is operated in a reversed manner for a time given by a timer, so that the door is moved back to a position near the half-latch position thereby to facilitate the removal of the foreign thing.
