Abstract: To further reduce the space required for installation, and to facilitate installation of a device for opening and closing a door by the stepping force of a pedestrian, the door-opening/closing device includes a step plate (2) provided with multiple bearings, a link (5) whose one end is coupled to a bearing (6) of the step plate (2), with the bearing (6) disposed in a metal part fixed on the floor and coupled to the other end of the link (5). The step plate (2) remains horizontal when stepped on, and moves downward in an arcuate manner in the direction in which the pedestrian is walking. The door (1) is opened and closed using this displacement (i.e., the step plate's downward movement) as a motive force. The return mechanism of the step plate (2) is composed of a link extender in which the other end side of the link (5) is extended in the direction opposite from the step plate (2), and a weight (7) that is axially supported on the extending-end part of the link extender. When a pedestrian steps on the step plate (2) the weight (7) rises and the step plate (2) moves downward; and, when the pedestrian steps off the step plate (2), the weight (7) moves downward due to its own weight and causes the step plate (2) to rise.
