To provide a joint fastening method in which preparation before fastening does not require labor and time, and management after fastening is facilitated.SOLUTION: A proper value of a gap G provided between a body (joint member) 31 and a nut 35 is preset. While measuring the gap G between the body 31 and the nut 35 by a sensor 3, the nut 35 is rotated by a fastening tool 2. Until an instructed value of a sensor 6 reaches a proper value, fastening is performed.SELECTED DRAWING: Figure 2 【課題】 締付け前の準備に手間が掛からず、また、締付け後の管理が容易となる継手締付け方法を提供する。【解決手段】 ボディ（継手部材）31とナット35との間にある隙間Gの適正値を予め設定しておく。ボディ31と35との間にある隙間Gをセンサ3によって測定しながら、ナット35を締付け工具2で回転させる。センサ6の指示値が適正値に達するまで締付けを行う。【選択図】 図２
