To detect the terminal end position of a moving body, and the an object a pinched by the moving body with a simple constitution by arranging a pressure sensitive sensor for detecting the terminal end of the moving body on an end part of a flat pressure sensitive sensor for detecting the pinching which is arranged on a tip part side of a movable part.

A pressure sensor 12 is arranged so that a tip part 15 is positioned inward of an edge 14 on the window opening side of a longitudinal seal wall 13, the tip part 15 side is a terminal end detection part 17 around a boundary 16, and the opposite side is a pinched detection part 18. When an object is pinched between an upper end 8 and an upper seal wall 11 in the process to close a window glass 2, the pressure is transmitted from a projection 10 to the sensor 12 by the pinching pressure, the pressure is detected by a detection part 18, and the elevation of the glass 2 is stopped. When no object is pinched by the glass 2, the upper edge 8 is uniformly pressed against the seal wall 11, and the detection part 17 detects the terminal end to close the window. The terminal end position of the glass 2 and pinching of the object by the glass 2 can be detected by one sensor 12.
