Abstract

A control unit for an electrically retractable door mirror includes a motor to drive rotationally a door mirror to a stored position or a normal position, a change-over switch, and first and second control circuits. The first and second control circuits include electronic switches respectively that are capable of switching on/off depending on the polarity of an electrical signal switched by the change-over switch. Excess current detecting devices, whose electrical resistances grow with an increase in a current, are connected to the electronic switches in series respectively. And, shutoff switches switch off the electronic switches respectively when a voltage generated in the excess current detecting devices exceeds a predetermined value.
