Abstract
A vertically movable workpiece support device has a drive chain bendable to only one side which supports a workpiece support base in a vertically linear path section. The drive chain extends from one end portion coupled to the workpiece support base to an intermediate portion engaging with a driving sprocket wheel. A chain guide plate which sandwiches, with the driving sprocket wheel, a link-to-link roller of the drive chain is arranged on an outer side of the driving sprocket wheel. A mark is displayed, on the side surface of the chain guide plate, in a position separated a certain distance outward from a turning path of links in the drive chain, and an opening portion for visually checking the mark is provided in a side wall which pivotally supports the driving sprocket wheel.
