Abstract
A pair of vertical guide rails of a workpiece transporting system are comprised of upper and lower rail portions, the upper rail portions being movable into axial alignment with the lower rail portions, the upper and lower rail portions being supported from a ceiling member of a building, and thus movable in unison with each other in the event of movement of the ceiling member of the building. A joint between the upper and lower rail portions of one guide rail is arranged at a vertical height different from that of the joint between the upper and lower rail portions of the other guide rail.
