1. A mirror for a vehicle, comprising:
a mirror surface;
an actuator which swivels the mirror surface;
at least one magnet which changes orientation by an angle in accordance with a variation in an inclined angle of the mirror surface when the actuator swivels the mirror surface;
at least one signal output unit which outputs a signal in accordance with the inclined angle of the mirror surface, based on the orientation of the magnet;
an interlocking member which changes an orientation in conjunction with the mirror surface, so that the orientation of the interlocking member is aligned with the orientation of the mirror surface;
at least one slide block being urged toward the interlocking member, and moving in a direction substantially perpendicular to the mirror surface by a distance in accordance with the variation in the inclined angle when the inclined angle of the mirror surface changes; and
at least one turning member which rotates by an angle in accordance with a moving distance of the slide block, when the slide block moves,
wherein the magnet is secured to the turning member and rotates in relation to the rotation of the turning member.
