Summary:PROBLEM TO BE SOLVED: To provide a joint structure of a pile, which makes the outside diameter of a joint section smaller than a pile diameter, and which prevents a void section from being formed between the buried pile and ground. SOLUTION: In the upper and lower piles 1 and 5, end plates 3 and 7 with a plurality of engaging protrusions 4 and 8 protruding from an peripheral edge are mounted on the end surfaces of connecting portions 2 and 6 with a diameter smaller than a pile diameter of an end of the pile. A ring 12 capable of being split into a plurality of pieces is fitted into the outsides of the connecting portions of the upper and lower piles in which the end plates are arranged while being brought into contact with each other in an opposed manner. Circumferential recessed grooves, which allow the fitting of the engaging protrusions 4 and 8 of both the upper and lower end plates arranged while being brought into contact with each other in an opposed manner, are formed in a plurality of inside protrusive streak portions which are vertically elongated at predetermined circumferential intervals inside the ring, respectively.
