To provide an extending/contracting mechanism of a work floor, which is configured to enable the work floor to be extended free of any step.SOLUTION: An extending/contracting mechanism of a work floor comprises: a main work floor 10; a sub work floor 21 that is stored below the main work floor 10 so that a surface of the floor is reversed downward; an expanding part 30 that expands the sub work floor 21 relatively toward outside of the main work floor 10 while reversing the surface of the sub work floor 21 upward; and a slip resistance rubber 40 (a height aligning part), which is laminated on the surface of the sub work floor 21 so that a floor surface of the main work floor 10 is flush with the floor surface of the sub work floor 21 arranged outside the main work floor 10, and which moves together with expansion of the sub work floor 21, in tandem with or following the expansion by the expanding part 30. Thereby, the mechanism can expand the work floor free of any step.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。【解決手段】作業床の拡縮機構は、主作業床10と、主作業床10の下側で、表面を下向きに反転した状態で収納される副作業床21と、主作業床10の外側に向けて副作業床21の表面を上向きに変えながら副作業床21を相対的に張り出させる張り出し部30と、主作業床10の床面と主作業床10の外側に配置される副作業床21の床面が同一高さになるように、副作業床21の表面に積層され、張り出し部30による張り出しに連動または追従して、副作業床21の張り出しとともに移動する滑り止めゴム40(高さ合わせ部)と、を備えることにより、段差無く作業床を拡張できる。【選択図】図1
