Abstract:
A lighting elevating apparatus includes: a reel coupled to a motor and rotated around an axis of a surface in a short direction of the reel including a reel wire reeling face and being arranged such that its longitudinal direction is in a vertical state; a reel wire to be reeled on the reel wire reeling face; a reeling guide including a reel wire touching part facing the reel wire reeling face and being arranged in parallel to the reel, wherein a distance between the reel wire reeling face and the reel wire touching part is equal or less than a diameter of the reel wire; and a connector attached to an end of the reel wire to connect an object, wherein the reeling guide counter-rotates, and the reel wire passes between the reel wire reeling face and the reel wire touching part.
