Summary:To provide a joint structure for steel pipe piles that facilitates connection work.SOLUTION: A joint structure includes a first joint connected to an end of a first steel pipe pile, a second joint connected to an end of a second steel pipe pile, and a pin, and is configured to connect the first joint and the second joint by the pin. The first joint and the second joint are provided with a pin hole penetrating both when they are fitted together. The pin comprises: a pin body inserted into the pin hole; a flexible portion provided at a tip of the pin body, having a larger diameter than that of the pin hole in an unloaded state, engaged with a peripheral edge of an inner peripheral side opening of the pin hole, and reduced in diameter when the pin body is inserted into the pin hole; and a projection formed on the other end of the pin body and engaged with a periphery of an outer peripheral side opening of the pin hole.SELECTED DRAWING: Figure 3 【課題】連結作業が容易な鋼管杭の接手構造を提案する。【解決手段】この発明の接手構造は、第１鋼管杭の端部に接続された第１接手と、第２鋼管杭の端部に接続された第２接手と、ピンとを備え、第１接手と第２接手とを前記ピンで連結するものであって、第１接手と第２接手には両者を嵌合したとき、両者を貫通するピン孔が備えられ、ピンはピン孔へ挿入されるピン本体と、ピン本体の先端部に設けられた可撓部であって、無負荷状態でピン孔より大径となりピン孔の内周側開口部の周縁に係合し、ピン本体をピン孔へ挿入する際には縮径する可撓部と、ピン本体の他端部に形成された突起であって、ピン孔の外周側開口部周縁に係合する突起と、を備えてなる。【選択図】 図３
