するパンタグラフ式昇降装置。 A lifter plate is provided at the upper end of a pair of lifter arms arranged in an X-shape, and the lower end of one lifter arm approaches and separates from the lower end of the other lifter arm using a horizontally arranged screw shaft driven by an electric motor. In the pantograph-type elevating device, in which the lifter plate is raised and lowered by moving the lifter plate upward and downward, there is a space between the screw shaft and a support member supporting the screw shaft, which is operated at a time other than when the lifter plate is moving upward. A pantograph type lifting device characterized by being provided with a friction type brake unit that applies braking force to the screw shaft using a surface perpendicular to the axis of the screw shaft as a friction surface.
