Abstract: PURPOSE:To provide a power window device by which accidents due to catch at the window can be avoided in advance even when a limit switch detecting the fully closed condition of the window has broken down and by which the load in catch is reduced even when it has caught something. CONSTITUTION:After a window has been moved up, when the detected number of accidents due to catch at the window reaches N times, it is judged that a limit switch 3 is out of order and the automatic moving-up function is restricted. And if the limit switch 3 is left 'ON' after the window has been moved up, it is judged that the limit switch is out of order and the automatic moving-up function is restricted. If the limit switch is left 'OFF' after the fully closed window has been moved down, it is judged that the limit switch is out of order and the automatic moving-up function is restricted. When a steady-state current in a motor 16 exceeds a basic figure A, it is judged as an overload state and further, when the varied quantity of the motor current within a certain time interval exceeds a basic figure B, it is also judged as an overloaded state.
