リフト。[Claims for Utility Model Registration] A hydraulic lift that relatively moves a first member having a first plane and a second member having a second plane opposite to the first plane, the hydraulic lift comprising: a hollow cylinder fixed to said first member perpendicularly to said cylinder for receiving pressurized fluid and sliding relative to said cylinder and relative to said cylinder so as to be able to be pushed from said cylinder towards said second member by said pressurized fluid; at least one stage of plungers, the plunger being movably inserted along the first plane; , a link mechanism which is coupled to the second member movably along the second plane at the other end and movably supports the first plane and the second plane parallel to each other; At least one of the at least one pair of links is pivotally connected to the final stage of the plungers at its pivot point, and one end of each of the pairs of links is connected to the second member. The legs are pivotally connected to the center of the leg portion on the second member side with respect to the pivot point, and the other ends thereof are mutually located at positions on a plane perpendicular to a plane including the axis of the cylinder and in which the pair of links extend. and a link mechanism having a pair of small links pivotally connected to the second member and movable in a direction perpendicular to the second plane.
