PROBLEM TO BE SOLVED: To provide an electric lifting device which makes a balance of loaded articles at an arbitrary position and makes a smooth operation in the case of lifting and lowering with a small force.SOLUTION: It comprises a placing stand part 21 placing articles 60, a lifting operation part 5 lifting the placing stand part 21, a lifting support part 20 fixing the lifting operation part 5, a motor part 6 transmitting power to the lifting operation part 5, weight detection means 15a-15d for detecting weight to be added to the placing stand part 21, position detection means 19 for detecting the lifting position of the placing stand part 21, a control part 10 commanding so as to balance the thrust to the placing stand part 21 generated by the lifting operation part and the vertically downward force that the placing stand part is subjected to, and a posture correction part correcting the lifting posture of the placing stand part. The posture correction part has multiple arms to expand and contract in the oscillatory state at least three or more vertical planes respectively as the expanding and contracting oscillation plane, and each expanding and contracting oscillation plane of each adjacent arm is provided so as to intersect with each other.SELECTED DRAWING: Figure 2
