Abstract:
1. A detector for detecting a foreign material caught between a an end portion of a movable body and a closed body, the detector in combination with an opening and closing mechanism and a movable body for movement in a closing movement direction with respect to such closed body, the movable body being for movement toward a closing direction at an angle with respect to the closing movement direction immediately before a closing movement direction end portion of the movable body reaches a closing movement end point located substantially at an orthogonal direction lateral side of such closed body with respect to the closing movement direction, and the movable body thus being for closing a gate located between the movable body and such closed body along the closing movement direction, the foreign material detector comprising: a pressure sensor, which is mounted on a movable body at a lateral side of the movable body along a substantially orthogonal direction with respect to the closing movement direction, for movement with the movable body, and for detection of a pressed reaction force effected by a foreign material when the pressure sensor presses against such foreign material; said pressure sensor comprising an exterior periphery and an interior periphery, said exterior and interior peripheries for deforming in a predetermined direction in response to such reaction force and being located closer to said closing movement end point than said end portion of the movable body, wherein said exterior periphery is further away from said closing movement end point than said interior periphery.
