Abstract
A method for facilitating fabrication of a coupling member includes a first step of boring one of upwardly open, passageways, a communication passageway and an auxiliary passageway in a body block, a second step of inserting a closure member into the auxiliary passageway, a third step of welding the closure member to the inner peripheral body portion defining the auxiliary passageway, and a fourth step of boring the other upwardly open passageway in the body block. The closure member is inserted in the second step so as to be positioned at least party in the portion where the other upwardly open passageway is to be formed.
