Abstract
An automatic opening-and-closing device can be obtained which can prevent a foreign object from being caught in by detecting the foreign object even if an opening/closing speed of a moving body changes or the foreign object is small. An automatic sliding door device 10 detects that there is an foreign object on a locus of sliding of a door panel 14, by detecting a pushing reaction force when a pressure sensitive sensor 60 pushes the foreign object at the time of forward sliding of the door panel 14 slides forward. Hence, even if the sliding speed of the door panel 14 changes, or even if the foreign object is small, the foreign object can be detected to thereby prevent the foreign object from being caught in the door. Moreover, with the automatic sliding door device 10, a code 80 is passed through inside of the door panel 14 and connected to a lower end portion of the pressure sensitive sensor 60 via a circular hole 110 formed at a lower end portion of the door panel 14. Hence, the detection range on the upper end side of the door panel 14 can be made wider, and management of the code 80 at the time of assembly becomes easy.
