The present invention is to provide a power regulated window having a window glass to be closed intentionally when some foreign body is pinched by the window glass for security reasons. When a close signal is output to a semiconductor switching element from window regulator switches, the window glass is closed. When some foreign body such as arm or fingers is pinched by the window glass, a load current of a motor becomes abnormal and the motor rotates reversely to open the window glass in order not to damage the foreign body. Besides this protective function, when the foreign body is pinched by the window glass and a prohibit signal to invalidate the reverse rotation is output, a reversing controller is stopped and the window glass is closed continuously by a bypass switching element.
