Abstract
PURPOSE:To prevent the shift of a mirror set position, by using a worm gear in the driving system of a mirror and moving the worm core in the direction of thrust to absorb displacement of the mirror shaft when the set position of the mirror is adjusted finely. CONSTITUTION:The set position of a mirror holder 1 is adjusted finely by bringing an adjusting screw 6 into contact with a stopper provided to the holder 1. When the adjusting screw 6 is moved forward and backward while being brought into contact with the holder 1 to adjust the optical position of the mirror, a shaft 10 of the holder 1 is rotated somewhat, and a worm wheel 5 is rotated somewhat, and by this displacement, a worm core 4 is moved in the direction of the core but is not rotated. Even if the worm core 4 is moved, the worm wheel 5 is driven accurately in the case, wherein the worm core is rotated and driven from the side of a motor 2, because both ends of the worm core are balanced by a spring 7.
