Claims

[Scope of utility model registration request]

An outer cylinder, a plurality of intermediate cylinder members having different diameters that are sequentially fitted inward within the outer cylinder, and a shaft member that is fitted concentrically to the innermost one of the intermediate cylinder members are provided. The outer cylinder, the plurality of intermediate cylinder members, and the shaft member are screwed together through threaded portions at the mutually overlapping portions, and the adjacent members are subjected to maximum contraction at maximum expansion and maximum contraction. What is claimed is: 1. A screw-type hoist device, characterized in that it is provided with a stopper mechanism that can lock the outer cylinder and the shaft member relative to each other, and is also equipped with a drive means that rotates the outer cylinder and the shaft member relative to each other.
