摘要： A joint construction for cable piping provided with an inner cylinder of thin wall pipe and an outer cylinder fitted on the inner cylinder as to freely slide to connect a first pipe for cable to a second pipe for cable as to freely expand and contract in length. A holding ring of a first seal member, tightly fit to a peripheral face of an end portion of the first pipe, a first stop ring of plate, hitching to the peripheral face of the end portion of the first pipe, and an opening end forming member, are unitedly fit by plastic working of an end of the inner cylinder. A holding groove of a second seal member, fit to a peripheral face of an end portion of the second pipe, is formed by plastic work of another end of the inner cylinder. A second stop ring, hitching on the peripheral face of the end portion of the second pipe, and an opening end forming member are unitedly fit by plastic work on an outer end side of the outer cylinder.
