Patent ID: 7759892

Claim:
A vehicle mirror device comprising: a base unit that is configured to be fixed to a vehicle; a body unit that includes a mirror, and is rotatably attached to the base unit; and a driving unit that drives the body unit to rotate with respect to the base unit, wherein the driving unit includes a motor that applies a driving force to the body unit to rotate the body unit; a current detecting circuit that detects current fluctuation that occurs due to rotation of the motor; and a switching circuit that switches ON or OFF current supply to the motor, while the current detecting circuit detects current fluctuation, the switching circuit keeps the current supply ON, and when the current detecting circuit detects no current fluctuation, the switching circuit switches OFF the current supply, the current detecting circuit includes a first current detecting circuit used when the mirror is retracted, and a second current detecting circuit used when the mirror is set up, the first current detecting circuit includes a first shunt resistance for detecting current fluctuation, and the second current detecting circuit includes a second shunt resistance for detecting current fluctuation, the driving unit further includes a first diode connected in parallel to the first shunt resistance, and a second diode connected in parallel to the second shunt resistance, and when a current flows in either one of the first shunt resistance and the second shunt resistance, current supply to the other one of the first shunt resistance and the second shunt resistance is cut off by the corresponding one of the first diode and the second diode.
