Abstract
In order to make it possible to ensure the axis alignment performance while reducing the processing cost, and to make a coupling structure compact to perform the coupling work and the detaching work of pipe members without difficulty even in a narrow work space, the coupling structure according to the invention includes a pipe coupling that couples a pair of pipe members each including a flange at an end portion in a state where the flanges of the pipe members face each other, an annular gasket interposed between the flanges of the pair of pipe members, and recesses formed individually in facing surfaces of the flanges facing each other, in which the annular gasket fitted into the respective recesses makes pipe axes of the pipe members and the annular gasket coincide with each other.
