PURPOSE:To detect lock of a window with high degree of accuracy by an electric current of a power window motor opening and closing the window. CONSTITUTION:In a lock detection auto holding circuit of a power window operated so as to stop a power window motor 1 automatically in the case an electric current supplied to the power window motor 1 opening and closing the window is detected by a shunt resistor 8 provided to an electric current detector 3 to continue an abnormal current for a certain period of time, electric current terminals 8b and 8c and voltage terminals 8a and 8d are provided to the shunt resistor 8 of the electric current detector 3. An electric current supplied to the power window motor 1 from the electric current terminals 8b and 8c is detected by the electric current terminals of the shunt resistor 8. Accordingly, the electric current supplied to the power window motor 1 can be detected with high degree of accuracy, so that reliability is promoted without having malfunction. |
