A lifting apparatus using a plate spring is provided to easily supply power from a base to a transfer support by inserting a power cable into the lifting apparatus through a hollow worm gear without a change of an appearance of the apparatus. A lifting apparatus using a plate spring includes a protrusion part frame(100), a protrusive plate spring(300), and a worm gear. The protrusion part frame includes a plurality of squeeze rollers and a pair of supporting plates. The squeeze rollers are arranged to be spaced apart from each other at regular intervals in a circumferential direction. The supporting plates support both ends of the squeeze rollers. The protrusive plate spring is contacted to inner sides of the squeeze rollers to be wound, and a wound end thereof is guided by a guide roller to be drawn upward. The worm gear is protruded upward through a hole of a base(2) and rotates by being powered by a driving motor(3). |
