PROBLEM TO BE SOLVED: To provide a lift device comprising a structure capable of reciprocating in two directions.SOLUTION: A lift device comprises: a left moving and retreating mechanism MR for moving and retreating a mount plate 30 in a left direction; and a right moving and retreating mechanism ML for moving and retreating the mount plate in a right direction. The left moving and retreating mechanism MR and the right moving and retreating mechanism ML comprise respectively, drive members 24R, 24L for moving and retreating in the left direction or the right direction corresponding to rotation of the respective drive shafts. The mount plate 30 comprises: a contact pin 32R for engaging with the drive member 24R; and a contact pin 32L for engaging with the drive member 24L. Regulation paths for regulating movement paths of the drive members 24R, 24L comprise respectively: a straight line groove LN extending in parallel to the axial direction of the drive shaft; and a bent groove BS reaching an origin position and coming close to the respective drive shaft from a regulation main line.SELECTED DRAWING: Figure 5 |
