Abstract
This invention prevents a power window from trapping a hand or the like during manual opening and closing of the window as well as during automatic opening and closing of the window. A current-flowing unit 56 flows a current in a closing direction in a power window motor 58 by turning on a sub-switch 57 for a passenger's seat window. While a catching detector 61 generates a detecting signal when an obstacle is present, a breaker 63 breaks a current flowing in a closing direction in the motor 58 through the unit 56 by turning off a master switch 39 for the passenger's seat. A reversing unit 65 rotates the motor 58 in a reverse direction by flowing a current in an opening direction in the motor 58. Even if an obstacle is present during an operation of closing the manual sub-switch 57, it is possible to release window, thereby freeing the obstacle.
