To provide an expansion and contraction mechanism of a work floor capable of expanding the work floor without step difference such that an operator can comfortably work on the expanded work floor without paying attention to a floor surface.SOLUTION: An expansion and contraction mechanism of a work floor includes a main work floor 1, a sub-work floor 2 provided below the main work floor 1, and a step difference eliminating plate 3 which has a tip part and a base end part and is rotatably supported by an upper side of the sub-work floor 2 around the base end part as its rotation center. The step difference eliminating plate 3 stands when the work floor is contracted. When the work floor is expanded, the step difference eliminating plate 3 is overlapped with the slid sub-work floor 2 so as to eliminate the step difference between a top surface of the main work floor 1 and a top surface of the sub-work floor 2.SELECTED DRAWING: Figure 1
【課題】作業床の拡縮機構において、段差無く作業床を拡張できるようにすることで、拡張された作業床で作業員が床面を気にすることなく快適に作業を行えるようにする。【解決手段】作業床の拡縮機構において、主作業床1と、主作業床1の下に設けた副作業床2と、先端部と基端部を有し、基端部を回転中心として副作業床2の上側で回転自在に支持された段差解消プレート3と、を備え、作業床の縮小状態では、段差解消プレート3が起立し、作業床の拡張状態では、スライドした副作業床2の上に段差解消プレート3を重ねて、主作業床1の上面と副作業床2の上面との間の段差を解消する。【選択図】図1
