Abstract
PURPOSE: To simplify the structure of a jack and to automatically lift articles and widening a space between the articles by pushing by setting as a fixed end one end of a shape memory alloy material bent on one plane where a memory shape is linear, and providing a seat in the other end thereof. CONSTITUTION: The nut 3 of a seat 5 is engaged with a screw 2 provided in one end of a shape memory alloy structural material 1 bent on one plane, and a seat 4 is directly joined to the other end thereof. This structural material 1 is heated by hot water or hot wind so as to exceed a transformation temperature, and then restored to be a linear shape as a memory shape. By this restoring force, an article is lifted, and a space between articles is pushed to be widened, and this space is maintained.
