Abstract
In a power window apparatus, when a controller determines that a captured foreign object, which is captured between a window glass and a window frame of a door, is present, the controller executes an interrupting process that interrupts a current operation of a drive mechanism. The controller does not determine whether the captured foreign object is present in an initial mask period that is a time period from a time point of starting rotation of the electric motor to a time point, at which a rotational speed of the electric motor reaches a stable state. The initial mask period is variable based on an operational load of the electric motor.
