PROBLEM TO BE SOLVED: To provide a pile head joint structure, the joint part of which can acquire strength. SOLUTION: A joint body 3, in which a hollow part of a tire 31 is filled with a filler, is arranged a pile head 11 of a pile body 1 and an upper structure (foundation 2). Thus, since the joint body 3 is arranged between the pile body 1 and the foundation 2 so that the pile body 1 and the foundation 2 cannot be directly joined together, stress (such as bending moment), acting on the pile body 1, can be greatly reduced. The filler, which is infilled into the hollow part of the tire 31, reduces an input earthquake motion by the base isolation effect of absorbing earthquake motion energy by shear deformation. Furthermore, during earthquakes, since lift such as rocking (standing on tiptoes) is permitted, the earthquake motion input into the upper structure can be reduced. Particularly, since the joint body 3, in which the hollow part of the tire 31 is filled with the filler, acquires high strength, it can be utilized even for a large-scale structure.
