The present invention relates to a stage elevator. According to the present invention, an elevating body that supports, lifts, and lowers a stage is stably supported by a guide frame during an elevation operation and the guide frame is simplified in structure for the ease of manufacturing. Also, the volume is minimized for the ease of installation and the stage can be utilized to the maximum extent. The present invention includes the vertically disposed guide frame; and the elevating body with an upper portion coupled with the stage and both sides provided with a pair of first guide rollers coupled to protrude, the elevating body being lifted and lowered along the guide frame. The guide frame has a pair of first supporting portions that are formed to be bent inside from both side plate end portions to form an opening portion communicating with a hollow portion and a pair of second supporting portions that are formed to protrude from inner side surfaces of both side plates. The elevation of the elevating body is guided as the first guide rollers are supported in contact with the respective supporting portions while being coupled between the first and second supporting portions. |
