CA 2443335

An opening/closing apparatus including a trapping detection structure which reliably implements detection of trapping of foreign objects, even at a structure at which an outer peripheral edge of a moving body or an inner peripheral edge of an opening includes corner portions with small radii of curvature. A pressure sensor which detects external forces from directions intersecting a length direction thereof is provided at an outer periphery portion of a back door. However, at a corner portion, at a lower end portion of a door side portion or the like, the pressure sensor is provided with a large curvature such that the pressure sensor keeps distant from the corner portion. In place thereof, another pressure sensor, with a facing pair of electrode sheets, is provided along the corner portion. When one or more of these pressure sensors detects an external force, the back door is moved for opening.
