PROBLEM TO BE SOLVED: To obtain sufficient bearing power by a pile with a comparatively simple structure in supporting a concrete foundation by the pile, and to suppress bending stress generated to a pile head and the foundation to reduce the cross section of the pile and foundation and to further prevent the damage of the pile head. SOLUTION: The upper end of the pile 1 opened at the upper end is supported abutting against a bottom face 2a of the concrete foundation 2. The transmission of tensile force is thereby suppressed to reduce the bending moment of the pile head. A cup-shaped closing member 3 is mounted on the upper end of the pile 1, and a part of the concrete foundation 2 projects into the pile 1 using the closing member 3 as a form to secure the transmission ability of horizontal external force by the projecting part 2b. Further, the lower part of the projecting part 2b is not brought into contact with an internal wall 1c of the pile 1 to suppress the generation of bending moment by the so-called leverage.
