PROBLEM TO BE SOLVED: To provide a supporter which is installed easily to a pile head and by which the supporting height of a foundation can be adjusted easily and accurately and differential settlement can be corrected at a low cost in a short construction time even when the differential settlement occurs in a building. SOLUTION: A foundation supporter for the building has a first screw body 2 fixed on the pile 5 head side and a second screw body 3 screwed to the first screw body 2 and bearing the underside of a foundation 6 for the building. The second screw body 3 is moved vertically to the first screw body 2, and the whole supporter 1 is expanded and contracted in the axial direction by forwardly and reversely rotating the second screw body, and the supporting height of the foundation 6 is adjusted.
