PURPOSE: A jacking apparatus of leg is provided to rotate a rotational cylinder, thereby more precisely controlling the location of leg. CONSTITUTION: A jacking apparatus of leg includes a leg (300), a rotational cylinder (100), and a guide (200). The leg is vertically movable with respect to a ship body, and a protrusion (310) is formed on the one side of leg. The rotational cylinder surrounds at least one leg from the outside, an insertion portion into which the protrusion of leg is inserted is formed on the inner circumferential surface. The guide guides the protrusion of leg so that the leg vertically ascends or descends when the rotational cylinder is rotated. |
