Zusammenfassung:	PURPOSE: To facilitate lifting by fixing a screw so that it is not rotated after placing the lower part of a box main body on a nut screwed with multiple screws and rotating the nut interlockingly with a drive force transmission member so as to lift the box main body. CONSTITUTION: When a motor 5 is operated, a drive gear 7 is rotated to run a timing belt 4. Next the belt 4 is engaged with the gear of a nut 2, and the nut 2 is rotated around a screw 1 and moved in the vertical direction. Also a support part 3 and a box type main body 5 are moved in the vertical direction integrally with the nut 2. In this case, the nut 2 is rotated by the same number of rotations to lift the same amount so as to move the main body 6 evenly to a desired position. Thus the mechanism of a lifting device can be simplified, and a large box body can be lifted evenly and easily.
