Abstract
To provide a structure supporting apparatus that enables an upper structure to be lifted up to a precise position with respect to a lower structure in a simple and reliable manner and also can be used as a supporting member as it is without fitting any stop members or equivalent, to provide improved workability. In a structure supporting apparatus in which an upper pressure-bearing member and a lower pressure-bearing member is moved relative to each other in the state of being laid one on another to vary the thickness of the upper pressure-bearing member and the lower pressure-bearing member in an overlaying direction, a driving device for driving the lower pressure-bearing member is so constructed that power input from a drive shaft can be transmitted to a feed screw through a reduction gear mechanism including intermediate gear elements.
