PROBLEM TO BE SOLVED: To reduce the erroneous operation of a power window without depending upon the site of a window frame in the power window, in which a foreign matter held between the window frame and a window glass is sensed and the closing operation of the window glass is interrupted. SOLUTION: When a sensor signal 2b disposed to a rear side 11c is emitted, the holding of a foreign matter is decided on the basis of the sensor signal 2b without considering an overload signal 3a. When a sensor signal 2c arranged to an upper side 11a and a front side 11b is emitted, the holding of a foreign matter is decided on the basis of the overload signal 3a and the sensor signal 2b. Accordingly, since the holding of the foreign matter is judged on the basis of information, in which no error is contained in the decision of the holding of the foreign matter, at a site, where a working angle having the high rate of the occupying of a detection error is a specified working angle or less, the holding of the foreign matter is judged surely, and the erroneous operation of a power window is reduced. |
