In the conventional X-linked lift mechanism lifting frame type for driving the lifting element in a state where a large area falling it is difficult to place the mechanism elements of the other features because it occupies a discard. In addition, the direct-acting actuator of the construction so as to raise the lifting frame according to the operation of the drawing direction is dangerous because when the direct acting actuator is broken discard lifting frame is dropped. In the present invention, the base frame 1 and the lifting frame (2) in the lifting mechanism with a second of the first link 3, the second link 4 constituting the X-linked mechanism between, on the other end of the second link boost to the drive member 11 is installed to enable rotational movement arm 12 and drive arm 13 is installed, and a slide guide to lift the moving element installation guide 14 to the end portion of the arm member 15 installed in the longitudinal direction at the other end of the first link, and solve the above problems by configuring the linear motion actuator 16, the X-link type lifting mechanism installed between the other end of the drive arm and the first link. ; base frame, lifting frame, link, movement members, guidance member, the drive member, the drive arm, the direct acting actuator, X link type lifting mechanism
