Abstract: 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.

Abstract: Provided is an improved stopper structure for defining both opening and closing limits of a lid member such as a trunk lid of an automobile requiring only a minimum number of component parts and a minimum amount of work for the fabrication process. The stopper for defining the opening and closing limits of a lid member attached to a vehicle body via a four-link mechanism 1 comprises a stopper member secured to an inner surface of the lid member, a first abutting surface provided in one of the link arms for engaging the stopper member when the lid member is opened up, and a second abutting surface provided on the vehicle body for engaging the stopper member when the lid member is fully closed. In particular, it is preferable to provide the stopper member with a plurality of contact surfaces having different heights substantially symmetrically around a mounting portion thereof.

Abstract: A striker for a lid of a fuel inlet chamber, which is remotely controllable through a control cable. The striker comprises a lock pin, a spring and an inner cable of the control cable. The lock pin is movable in the axial direction thereof and rotatable around a rotational axis, and the rotation of the lock pin can be locked to an aimed position. The lock pin is urged to be projected inside the fuel inlet chamber by the spring. The inner cable is used for withdrawing the lock pin backward.
