Abstract

PURPOSE: To produce a threaded joint easily and inexpensively by forming the entire part of cylindrical threaded joints, which are axially long, descretely to a shape bisected axially including the female thread of the inside then coupling these into one body.
CONSTITUTION: The entire shape of a joint constituting member 1 assumes a trough shape provided with a recess surface 2 of a semicircle in the section perpendicular to the axial direction. Thread grooves 3 of such a style that female threads are bisected axially are formed on the recess surface 2; if necessary, a recess 4 of such a shape that the cavity part 1 larger in diameter than the inside diameter of the female thread is bisected axially is also formed. Such member 1 is formed by plastic working by roll forming or pressing including the thread grooves 3 and recess 4. Next, two pieces of these members 1 in a pair are held bitted face to face and in this state they are welded 5, for example, intermittently, whereby they are coupled into one body.
