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

    【課題】載せ置く物品を任意の位置でバランスさせ、小さな力で昇降移動させる際の操作を円滑にする電動昇降装置を提供することを課題としている。【解決手段】物品60を載せ置く置き台部21と、置き台部21の昇降を行う昇降作動部5と、昇降作動部5を支持固定する昇降支持部20と、昇降作動部5へ動力を伝達するモータ部6と、置き台部21に印加される重量を検出する重量検出手段15a〜15dと、置き台部21の昇降位置を検出する位置検出手段19と、昇降作動部が発生させる置き台部21への推力と置き台部が受ける鉛直下向きの力をバランスさせるように指令を行う制御部10と、置き台部の昇降の姿勢を矯正する姿勢矯正部と、を備え、姿勢矯正部は少なくとも3面以上の鉛直平面を伸縮揺動面としてそれぞれ伸縮揺動する複数のアームを有し、隣り合う各アームの各伸縮揺動面は交差するように設けられている。【選択図】図2
