ABSTRACT:
A power window device includes window glass, an elevating mechanism, and a control device for detecting pinching of a foreign object by the window glass. The control device calculates an amount (a rotation speed variation ΣΔωα) of the pinching based on a variation amount of an opening/closing speed of the window glass, and estimates the amount (a rotation speed variation ΣΔωβ) of the pinching before the opening/closing speed changes due to the pinching. The control device determines the pinching of the foreign object based on these pinching calculation and estimation amounts.
