PROBLEM TO BE SOLVED: To provide a pantograph type jack excellent in productivity, smoothness of lifting function and storage performance even with a short screw rod by improving the part of a female screw metal.SOLUTION: In a pantograph type jack where a cargo receiving deck and a base are arranged vertically with right, left, and upper arms coupled in a pantograph shape with right, left, and lower arms by a left side coupling member and a right side coupling member, and a screw rod extended between both the left side coupling member and the right side coupling member to make the cargo receiving deck move vertically with respect to the base by expanding and contracting both the left side coupling member and the right side coupling member by rotation of the screw rod, the left side coupling member is provided in a female screw auxiliary cylinder with a female screw shaft constituting the support shaft part of the same and a female screw auxiliary cylinder having a female screw part in the extension part on the right side coupling member side, and a whirl-stop frame serving as the whirl-stop against the female screw.SELECTED DRAWING: Figure 6

    【課題】本発明のパンタグラフ式ジャッキは、本発明は、雌ネジメタルの部分を改良し、ネジ棒が短くても、生産性と昇降機能の円滑性と格納の性能に優れるパンタグラフ式ジャッキを提供する。【解決手段】荷受台と基台が上下に配され、その間に左右上アームと左右下アームがパンタグラフ状に左側連結部材と右側連結部材とにより連結され、両左側連結部材と右側連結部材間にネジ棒が差渡され、該ネジ棒の回転により両左側連結部材と右側連結部材間を拡縮し、基台に対して荷受台を昇降するパンタグラフ式ジャッキにおいて、前記左側連結部材は、その支軸部を構成するメネジ軸と、右側連結部材側の延長部に雌ネジ部を備えるメネジ補助筒体と、メネジ軸に対して回り止めとなる回止め枠がメネジ補助筒体に設けられてなる。【選択図】図6
