PROBLEM TO BE SOLVED: To provide a pantograph type jack of which stability at the time of rising is promoted, and a jack follows rising of a vehicle to suppress bending of respective parts of the jack, for reduction in weight as a whole and smooth rising/lowering operation.SOLUTION: In a pantograph type jack, a bottom plate part of a base includes a planar central outside surface part having a width required for self-supporting, and a left side outside surface part and a right side outside surface part which are connected on both left and right sides of the central outside surface part, with an inclination angle generated when a vehicle is jacked up formed to be an arc-like plane of a cylindrical surface having a width and radius allowing turn by contacting to a load surface.
【課題】本発明は、起立時の安定性を図り、ジャッキを車両の上昇に追従させてジャッキの各部の曲りを抑えて全体の軽量化とスムーズな昇降作動を行えるパンタグラフ型ジャッキを提供することにある。【解決手段】ベースの底板部が、自立に必要とする幅の平面状の中央外面部と、その中央外面部の左右の両側に接続し、車両扛重に生じる傾斜角を路面に接面して転回可能な幅と半径の円柱面の弧状面に形成される左側外面部と右側外面部から形成されるパンタグラフ型ジャッキ。【選択図】図6
