ABSTRACT:
A vehicle mirror comprises a mirror surface; a plate pivot110which tilts the mirror surface by tilting the plate pivot itself,a housing120which covers the plate pivot facing to the rear surface of the mirror surface across the plate pivot, which possesses a bottom portion substantially parallel to the plate pivot, and a curved side wall which is brought into contact with the side surface of the plate pivot to guide the side surface; an adjust nut108which is provided between the housing and the plate pivot, and which moves toward or backward to the rear surface of the pivot to tilt the plate pivot; a rotational variable resistor118which is provided between the housing and the plate pivot, and whose resistance value is varied depending on the rotation amount of a rotor that rotates depending upon the movement of the adjust nut; and a signal outputting portion124, which outputs a signal corresponding to the titled angle of the mirror surface depending upon the resistance of the rotational variable resistor.
