<P>PROBLEM TO BE SOLVED: To provide a structure for connecting steel pipe sheet piles and capable of sufficiently removing and cleaning earth and sand in a joint fitting space and efficiently performing the work of filling a filler while having a high shear capacity. Ž<P>SOLUTION: Steel pipe sheet piles are connected to each other via joints 11 and 12 mounted to main pipes 10 of steel pipe sheet piles, and mortar is filled in a space formed inside the joints 11 and 12. One joint 11 comprises a pair of L-shaped steel products 11a, and the other joint 12 comprises a steel pipe 12a for joints having a closed cross section. A protrusion 14 for adhesion with the mortar is provided for a part of the outer circumferential surface of a pain pipe 10 of steel pipe sheet piles between the L-shaped steel products 11a and 11a, and a protrusion 15 is also provided for the outer circumferential surface of the steel pipe 12a for joints.
