ABSTRACT:
A first pipe is press-fitted into a second pipe having an inner peripheral surface, circular in section, about an axis of the second pipe. The first pipe, having an outer peripheral surface provided with recesses each located between arcuate portions, and which recesses have the same radius about an axis of the first pipe and are located at a plurality of circumferentially spaced-apart points, The recesses are each located radially inwardly of a phantom circumferential extension of the arcuate portions to extend axially over a predetermined length of the first pipe. Thus, it is possible to relatively enlarge the press-fit margin leading to an elongation limit and to set the dimensional accuracy of the pipe product at a relatively low value by the fact that when the first pipe is press-fitted into the second pipe, the second pipe flows so as to fill a gap produced between the first and second pipes due to the plurality of recesses provided on the outer peripheral surface of the first pipe, as well as by the fact that the first pipe is easy to deform under compression at the recesses.
