Abstract

Disclosed is an apparatus for threadedly fitting a buttress tapered external thread portion and a buttress tapered internal thread portion each other. A detecting internal thread portion provided on the gauge is threadedly fitted into the buttress tapered external thread portion, and the buttress tapered internal thread portion is threadedly fitted into a detecting external thread portion provided on the gauge. As a consequence, a helical locus position of the tapered external thread portion and a helical locus position of the tapered internal thread portion are detected. Next, after the gauge has been removed and in the state wherein the thus detected helical locus positions are put in order each other, the tapered external thread portion and the tapered internal thread portion are relatively turned whereby these tapered external thread portion and tapered internal thread portion are threadedly fitted each other.
