位置検出装置。A mirror drive shaft is connected via a universal joint to the back surface of a mirror unit provided in a mirror housing so as to be tiltable, and the electric remote control tilts the mirror unit to a predetermined position by moving the mirror drive shaft forward and backward. In the mirror position control device, a magnetic body is fixed to the rear end of the mirror drive shaft, and a magnetic sensing element is disposed at a position opposite to the magnetic body, so that the mirror drive shaft moves forward and backward as the mirror drive shaft moves forward and backward. Magnetic materials and magnetically sensitive elements
A mirror position detection device characterized in that the mirror position is detected by converting the displacement of the mirror integrally into a change in the output signal from the magnetically sensitive element by changing the distance between the mirror and the mirror.
