Disclosed is an up-and-down driving device comprising a driving means, a fixed-position compression spring main module, and a variable-position compression spring supplemental module. The up-and-down driving device is configured to allow an up-and-down driving unit 150 to move while supporting the load of an object, in a support module 90 in which the up-and-down driving unit 150 is movably inserted into an inner space of a fixed housing 120, the up-and-down driving device comprising: a driving means configured to move the up-and-down driving unit 150 in an up-and-down direction; a fixed-position compression spring main module 100 comprising a fixed-position compression spring 130 having one side fixed to a lower end of the housing 120 and the other side supporting the up-and-down driving unit 150 and mounted in a motion direction of the up-and-down driving unit 150; and a variable-position compression spring supplemental module 200 comprising a variable-position compression spring 250 having one side mounted rotatably to a side of the housing 120 and the other side fastened rotatably to the up-and-down driving unit 150 and configured to rotate while making a predetermined angle with the motion direction of the up-and-down driving unit 150.
