PROBLEM TO BE SOLVED: To provide a compact lifting device while keeping rigidity to fluctuation of load and unbalanced load.SOLUTION: In a lifting device 10, a first guide mechanism 14 is provided in one recessed space 12c of a support 12 having an H-shape in cross section, and a screw mechanism 16 and a second guide mechanism 15 are provided in the other recessed space 12c of the support 12. Accordingly, the lifting device 10 is compact and has rigidity to load and unbalanced load, more particularly, rigidity in a horizontal direction (twisting direction), by effectively using the two recessed spaces of the support 12. |
