PROBLEM TO BE SOLVED: To provide an electric lift table which can secure a stroke over two times as high as from a seating position to a standing position by one table. SOLUTION: A front link mechanism comprising a first front lower link FL1, a second front lower link FL2, a first front upper link FU1 and a second front upper link FU2, and a back link mechanism comprising a first back lower link, a second back lower link, a first back upper link and a second back upper link are placed in parallel at a prescribed distance. Lower parts of the first front upper link FU1 and the first back upper link are integrally fastened by a slide. Lower parts of the second front upper link FU2 and the second back upper link are integrally fastened by a slide. A right-left integrated screw is turned by an electric motor to change distances between slides to turn and slide links, adjusting vertical position of the upper frame F2 with respect to the lower frame F1.
