An up-and-down driving device allows an up-and-down driving unit to move while supporting an object's load, in a support module in which the up-and-down driving unit is movably inserted into an inner space of a fixed housing. The up-and-down driving device includes: a driving means for moving the up-and-down driving unit in an up-and-down direction; a fixed-position compression spring main module including a fixed-position compression spring having one side fixed to a lower end of the housing and the other side supporting the up-and-down driving unit and mounted in a motion direction of the up-and-down driving unit; and a variable-position compression spring supplemental module including a variable-position compression spring having one side mounted rotatably to a side of the housing and the other side fastened rotatably to the up-and-down driving unit and configured to rotate while making a predetermined angle with the motion direction of the up-and-down driving unit.
