A power window apparatus is controlled by comparing present rotational frequency of a motor with a reference value selected depending on a present position of a window glass among plural reference values predetermined at every position of the window glass, supplying an electric current to the motor in the closing direction of a window when the present rotational frequency of the motor is larger than selected reference value, supplying the electric current to the motor in the opening direction of the window when the present rotational frequency is not larger than the selected reference value and the window glass does not arrive in a full-closed position, and cutting the current supply to the motor when the present rotational frequency is not larger than the selected reference value and the window glass arrives in the full-closed position.
