1. A vehicle mirror apparatus comprising: a tilting device tilting a mirror to adjust a tilting angle of the mirror; and a mirror surface angle detection device detecting the tilting angle of the mirror,
the tilting device including a base member, a tilting member supporting the mirror on the base member in such a manner that the mirror being tiltable around a predetermined tilting center, a male thread member provided so as to stand on the base member, a nut member having a rear end being rotatably screwed on and covering a free end of the male thread member and a front end rotatably connected to a position in the tilting member, the position being off the tilting center of the tilting member, and a drive device reversibly rotating the nut member to move the nut member along the male thread member to tilt the tilting member, the mirror surface angle detection device including a communication hole provided in the male thread member along a shaft axis of the male thread member, a mover inserted through the communication hole so as to be movable in an axial direction thereof, the mover having a front end connected to the nut member at a position in a back of the front end of the nut member so as to be rotatable relative to the nut member around an axis of the nut member, the mover moving following the nut member along the male thread member in such a manner that rotation of the mover relative to the male thread member being prevented, and a position detection device detecting a position of the mover in a direction along the male thread member relative to the base member. |
