To provide a device for detecting the insertion and final end of a power window by which the insertion is detected easily at an initial stage and the further insertion is prevented and also it is prevented that a strong force is exerted at the close finish stage of the power window and the expansion of a door member is prevented.

In the control device of the power window of an automobile, a cavity 22 is formed on the upper part being contact with the window frame 20 of a glass run 21 mounted on the upper inside of the window frame 20 and a pressure sensitive sensor PS in which an electric resistance value is changed by a pressure is arranged in the cavity 22 and also a voltage detection means for detecting the voltage V of the pressure sensitive sensor PS is provided and a calculation device of judging the insertion of a body between the window glass 24 and the upper part of the window frame 20 and the final reach of the window glass 24 by using the flange form of a voltage value after the voltage V of the pressure sensitive sensor PS at the close process of a window glass 24 beings to drop and its absolute value, is provided.
