Abstract
A lens moving mechanism includes a lens mount unit on which a lens for projecting light is mounted, a lens guide unit which supports the lens mount unit and guides the lens mount unit in at least one axis direction among three orthogonal axis directions including an optical axis direction of the light, and a lens guide fixing unit to which the lens guide unit is fixed. The lens guide unit includes a plurality of linear motion guide devices each including a track body fixed to the lens guide fixing unit and a moving body moving along the track body. A plurality of track bodies are coaxially disposed in the lens guide fixing unit.
