To provide an electric lift device capable of raising and lowering a table to a high level without increasing the diameter of the screw shaft.SOLUTION: An electric lift device 1 has a base 10 and a table 20 provided above the base 10. Between the base 10 and the table 20, a lower X link 30 and an upper X link 50 are provided, which are connected to each other. A lower drive unit 60 having a lower screw shaft 61 and a lower nut 62 that are screwed together is connected to the lower X link 30. An upper drive unit 65 having an upper screw shaft 66 and an upper nut 67 that are screwed together is connected to the upper X link 50. A gear group 70 is provided between the lower drive unit 60 and the upper drive unit 65. An electric motor 80 that powers the gear group 70 is provided. The gear group 70 transmits the power from the electric motor 80 to the lower drive unit 60 as a rotational force in a first direction. The gear group 70 simultaneously transmits a rotational force in a second direction opposite to the first direction to the upper drive unit 65. The table 20 is raised and lowered by the lower drive unit 60 and the upper drive unit 65.SELECTED DRAWING: Figure 1

    【課題】ねじ軸の軸径を太くすることなく、テーブルを高揚程に昇降できる電動リフト装置を提供すること。【解決手段】電動リフト装置1は、基台10と、基台10の上方に設けられるテーブル20を有する。基台10とテーブル20の間には、相互に連結される下Xリンク30と上Xリンク50が設けられる。相互に螺合する下ねじ軸61と下ナット62を備える下駆動部60が下Xリンク30に連結される。相互に螺合する上ねじ軸66と上ナット67を備える上駆動部65が上Xリンク50に連結される。下駆動部60と上駆動部65の間に歯車群70が設けられる。歯車群70に動力を与える電動モータ80が設けられる。歯車群70は、電動モータ80からの動力を下駆動部60に第1方向の回転力を伝える。歯車群70は、同時に上駆動部65に第1方向と反対の第2方向の回転力を伝える。下駆動部60と上駆動部65によってテーブル20が昇降動される。【選択図】図1
