Pipe joint

A pipe joint is provided that effectively accommodates a relative positional displacement between pipes, thereby allowing unfailing coupling between the pipes. The pipe joint is provided with a flexible pipe main body in a circular cylindrical shape; a pair of flanges that is provided on both ends the pipe main body, and are coupled to end portions of the first pipe and the second pipe that face each other; and a plurality of string members that couple the flanges. Each string member includes a string main body and a pair of stopping members that are provided on both ends of the string main body with a predetermined distance, and the flanges are formed in an annular shape and include a plurality of flange pieces that are separately formed, an ear portion having a coupling hole for coupling the flange pieces, a coupling bolt that couples the flange pieces, and the application bolt that couples the first pipe and the second pipe. The coupling bolt and/or the application bolt is provided with a through hole through which the string main body is inserted in the length direction, and a housing portion communicating with the through hole and having an opening area wider than that of the through hole.
