5. A vehicle mirror comprising:
a mirror surface;
an actuator configured to tilt the mirror surface;
an interlocking member configured to change a direction together with the mirror surface;
a spring positioned to generate a pressing force due to a tilting movement of the mirror surface;
a pressure sensor configured to detect the pressing force generated by the spring; and
a signal outputting device configured to output a signal based on the pressing force detected by the pressure sensor;
wherein the actuator comprises a slide rod configured to move toward or backward from a rear surface of the mirror surface to tilt the mirror surface, and the spring is at least partly inserted into the slide rod to apply a resilient force to the interlocking member via the slide rod.
