PROBLEM TO BE SOLVED: To provide a foundation beating metal fitting by which movement in a pile axial direction can be regulated and also movement in a direction orthogonal to the pile axial direction can be regulated.SOLUTION: An inventive foundation beating metal fitting 1 is provided with a hollow pile body 100 in which a column of a building structure is erected, and a part of the pile body 100 is buried underground. The pile body 100 includes: a ground side hollow part 110 of which a part is disposed on the ground; an underground hollow part 120 which is connected to a lower end 111 of the ground side hollow part 110 and all of which is disposed in the ground; and a tip 130 connected to a lower end 124 of the underground hollow part 120, and moving between an initial position where the tip 130 is the farthest away from the ground side hollow part 110 and a retreat position where the tip 130 most closely approaches the ground side hollow part 110. The underground hollow part 120 is expanded more than an outer peripheral wall 113 of the ground side hollow part 110 in association with movement of the tip 130 from the initial position to the retreat position. |
