<P>PROBLEM TO BE SOLVED: To provide a power window for a power window which can control the ascent or descent of window glass by detecting the sandwiching of an obstacle with accuracy even in case that an element for prevention of reverse connection of a battery is inserted. <P>SOLUTION: In a drive unit for a power window, which is equipped with a control circuit for performing the control of driving the power window by supplying a motor M1 for the drive of the power window with power voltage of a battery for a vehicle and stopping or inverting the drive motor M1 in question when a current increase occurs in the drive motor M1, a shunt resistor Rs for detecting the current flowing through the drive motor M1 as a voltage value is interposed between the drive motor M1 and the ground, and besides a diode D1 for protection at reverse connection of power is provided between the plus side of the power voltage VB and the control circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
