Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the wrong detection of the state of a bitten foreign matter due to a fluctuation in a motor load corresponding to a closing position determined on the curvature of a window glass in the case of detecting the state of the bitten foreign matter when the period of a pulse signal synchronized with the rotation of a driving motor exceeds a threshold value at the time of closing a window glass. SOLUTION: In this power window device to detect the state of a bitten foreign matter when the period of a pulse signal synchronized with the rotation of a driving motor in a window glass opening and closing mechanism exceeds a threshold value, the device is provided with a means for variably setting the threshold value according to the closing position of the window glass detected by counting the number of a pulse signal.
