<p>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.</p> |
