Abstract
When a window lowering switch is operated, a car voltage is supplied to a window lowering relay to drive the window lowering relay, and the window lowering relay is inhibited from being driven by supplying an inverse voltage to a window elevating relay. Thus, there is provided a waterproof power window device in which a window may be opened by operating the window lowering switch (3) even when a car falls in the water and is laid under water.
