To provide a lifting device which has a relatively simply configuration and is compact while suppressing reverse rotation in a power-off state.SOLUTION: This lifting device comprises a motor 11, circular support members 14-1, 14-2 that apply tensile force to two wires 4-1, 4-2 connected to the load, power transmission members 12-1, 12-2 that rotate about the rotation axis Ax by driving force of the motor 11, a guide mechanism that slidably holds the circular support members 14-1, 14-2 in a given range along the radial direction with respect to the rotation axis Ax, and electromagnets 13-1, 13-2 that use electromagnetic force to forcibly dispose the circular support members 14-1, 14-2 at a position where the center axes Ac1, Ac2 of the circular support members 14-1, 14-2 and the rotation axis Ax coincide with each other in the given range.SELECTED DRAWING: Figure 2

    【課題】 電源断状態での逆転を抑制しつつ比較的簡単な構成でコンパクトなリフト装置を得る。【解決手段】 このリフト装置は、モーター11と、負荷に接続された2本のワイヤー4-1,14-2に対して引張力を与える円形支持部材14-1,14-2と、モーター11の駆動力によって回転軸Axを中心にして回転する動力伝達部材12-1,12-2と、回転軸Axに対する径方向に沿って所定の範囲で円形支持部材14-1,14-2をスライド可能に保持するガイド機構と、その所定の範囲において、円形支持部材14-1,14-2の中心軸Ac1,Ac2と回転軸Axとが一致する位置に円形支持部材14-1,14-2を電磁力で強制的に配置させる電磁石13-1,13-2とを備える。【選択図】 図2
