PROBLEM TO BE SOLVED: To provide a lift facility that can hold a posture of a lifting body with respect to a guide rail, which further can appropriately move up and down the lifting body at a twisted part of the guide rail.SOLUTION: Orthogonal cross sections 1Da and 1Db in an arbitrary point on a route reference line SL of a guide rail having a plurality of guide surfaces G have twisted parts in which relative positional relations of a plurality of sides are constant and whose postures around the route reference line SL consecutively vary. A lifting body comprises a pair of lifting units, which comprise roller supporting frames that support a guided roller group so that rotation shaft cores of a plurality of guided rollers R constituting the guided roller group are included in the same orthogonal cross sections 1Da and 1Db, arranged at intervals in a direction along the route reference line. Each of the lifting units supports the roller support frames turnably around a turning shaft K set at a region surrounded by the guided roller group, and the turning shaft K is orthogonal to the orthogonal cross sections including the respective rotation shaft cores of the guided roller R in the guided roller group.SELECTED DRAWING: Figure 7
【課題】案内レールに対する昇降体の姿勢を適切に保持できるものでありながら、案内レールのねじれ部分において昇降体を適切に昇降させることができる昇降設備を提供する。【解決手段】複数の案内面Gを備える案内レールの経路基準線上SLの任意の点における直交断面1Da、1Dbは、複数の辺の相対位置関係が一定であり且つその経路基準線SL周りでの姿勢が連続的に変化するねじれ部分を有し、昇降体は、被案内ローラ群を構成する複数の被案内ローラRの回転軸心が同一の直交断面1Da、1Dbに含まれるように被案内ローラ群を支持するローラ支持枠を備える一対の昇降ユニットを、経路基準線に沿う方向に間隔を隔て並べて備え、昇降ユニットの夫々は、被案内ローラ群に囲まれる領域に設定された回動軸K周りに回動自在にローラ支持枠を支持し、回動軸Kは被案内ローラ群における個々の被案内ローラRの回転軸心を含む直交断面に直交している。【選択図】図7
